Struct borsh::maybestd::rc::Rc1.0.0[][src]

pub struct Rc<T> where
    T: ?Sized
{ /* fields omitted */ }

A single-threaded reference-counting pointer. ‘Rc’ stands for ‘Reference Counted’.

See the module-level documentation for more details.

The inherent methods of Rc are all associated functions, which means that you have to call them as e.g., Rc::get_mut(&mut value) instead of value.get_mut(). This avoids conflicts with methods of the inner type T.

Implementations

impl<T> Rc<T>[src]

pub fn new(value: T) -> Rc<T>[src]

Constructs a new Rc<T>.

Examples

use std::rc::Rc;

let five = Rc::new(5);

pub fn new_cyclic(data_fn: impl FnOnce(&Weak<T>) -> T) -> Rc<T>[src]

🔬 This is a nightly-only experimental API. (arc_new_cyclic)

Constructs a new Rc<T> using a weak reference to itself. Attempting to upgrade the weak reference before this function returns will result in a None value. However, the weak reference may be cloned freely and stored for use at a later time.

Examples

#![feature(arc_new_cyclic)]
#![allow(dead_code)]
use std::rc::{Rc, Weak};

struct Gadget {
    self_weak: Weak<Self>,
    // ... more fields
}
impl Gadget {
    pub fn new() -> Rc<Self> {
        Rc::new_cyclic(|self_weak| {
            Gadget { self_weak: self_weak.clone(), /* ... */ }
        })
    }
}

pub fn new_uninit() -> Rc<MaybeUninit<T>>[src]

🔬 This is a nightly-only experimental API. (new_uninit)

Constructs a new Rc with uninitialized contents.

Examples

#![feature(new_uninit)]
#![feature(get_mut_unchecked)]

use std::rc::Rc;

let mut five = Rc::<u32>::new_uninit();

let five = unsafe {
    // Deferred initialization:
    Rc::get_mut_unchecked(&mut five).as_mut_ptr().write(5);

    five.assume_init()
};

assert_eq!(*five, 5)

pub fn new_zeroed() -> Rc<MaybeUninit<T>>[src]

🔬 This is a nightly-only experimental API. (new_uninit)

Constructs a new Rc with uninitialized contents, with the memory being filled with 0 bytes.

See MaybeUninit::zeroed for examples of correct and incorrect usage of this method.

Examples

#![feature(new_uninit)]

use std::rc::Rc;

let zero = Rc::<u32>::new_zeroed();
let zero = unsafe { zero.assume_init() };

assert_eq!(*zero, 0)

pub fn try_new(value: T) -> Result<Rc<T>, AllocError>[src]

🔬 This is a nightly-only experimental API. (allocator_api)

Constructs a new Rc<T>, returning an error if the allocation fails

Examples

#![feature(allocator_api)]
use std::rc::Rc;

let five = Rc::try_new(5);

pub fn try_new_uninit() -> Result<Rc<MaybeUninit<T>>, AllocError>[src]

🔬 This is a nightly-only experimental API. (allocator_api)

Constructs a new Rc with uninitialized contents, returning an error if the allocation fails

Examples

#![feature(allocator_api, new_uninit)]
#![feature(get_mut_unchecked)]

use std::rc::Rc;

let mut five = Rc::<u32>::try_new_uninit()?;

let five = unsafe {
    // Deferred initialization:
    Rc::get_mut_unchecked(&mut five).as_mut_ptr().write(5);

    five.assume_init()
};

assert_eq!(*five, 5);

pub fn try_new_zeroed() -> Result<Rc<MaybeUninit<T>>, AllocError>[src]

🔬 This is a nightly-only experimental API. (allocator_api)

Constructs a new Rc with uninitialized contents, with the memory being filled with 0 bytes, returning an error if the allocation fails

See MaybeUninit::zeroed for examples of correct and incorrect usage of this method.

Examples

#![feature(allocator_api, new_uninit)]

use std::rc::Rc;

let zero = Rc::<u32>::try_new_zeroed()?;
let zero = unsafe { zero.assume_init() };

assert_eq!(*zero, 0);

pub fn pin(value: T) -> Pin<Rc<T>>1.33.0[src]

Constructs a new Pin<Rc<T>>. If T does not implement Unpin, then value will be pinned in memory and unable to be moved.

pub fn try_unwrap(this: Rc<T>) -> Result<T, Rc<T>>1.4.0[src]

Returns the inner value, if the Rc has exactly one strong reference.

Otherwise, an Err is returned with the same Rc that was passed in.

This will succeed even if there are outstanding weak references.

Examples

use std::rc::Rc;

let x = Rc::new(3);
assert_eq!(Rc::try_unwrap(x), Ok(3));

let x = Rc::new(4);
let _y = Rc::clone(&x);
assert_eq!(*Rc::try_unwrap(x).unwrap_err(), 4);

impl<T> Rc<[T]>[src]

pub fn new_uninit_slice(len: usize) -> Rc<[MaybeUninit<T>]>[src]

🔬 This is a nightly-only experimental API. (new_uninit)

Constructs a new reference-counted slice with uninitialized contents.

Examples

#![feature(new_uninit)]
#![feature(get_mut_unchecked)]

use std::rc::Rc;

let mut values = Rc::<[u32]>::new_uninit_slice(3);

let values = unsafe {
    // Deferred initialization:
    Rc::get_mut_unchecked(&mut values)[0].as_mut_ptr().write(1);
    Rc::get_mut_unchecked(&mut values)[1].as_mut_ptr().write(2);
    Rc::get_mut_unchecked(&mut values)[2].as_mut_ptr().write(3);

    values.assume_init()
};

assert_eq!(*values, [1, 2, 3])

pub fn new_zeroed_slice(len: usize) -> Rc<[MaybeUninit<T>]>[src]

🔬 This is a nightly-only experimental API. (new_uninit)

Constructs a new reference-counted slice with uninitialized contents, with the memory being filled with 0 bytes.

See MaybeUninit::zeroed for examples of correct and incorrect usage of this method.

Examples

#![feature(new_uninit)]

use std::rc::Rc;

let values = Rc::<[u32]>::new_zeroed_slice(3);
let values = unsafe { values.assume_init() };

assert_eq!(*values, [0, 0, 0])

impl<T> Rc<MaybeUninit<T>>[src]

pub unsafe fn assume_init(self) -> Rc<T>[src]

🔬 This is a nightly-only experimental API. (new_uninit)

Converts to Rc<T>.

Safety

As with MaybeUninit::assume_init, it is up to the caller to guarantee that the inner value really is in an initialized state. Calling this when the content is not yet fully initialized causes immediate undefined behavior.

Examples

#![feature(new_uninit)]
#![feature(get_mut_unchecked)]

use std::rc::Rc;

let mut five = Rc::<u32>::new_uninit();

let five = unsafe {
    // Deferred initialization:
    Rc::get_mut_unchecked(&mut five).as_mut_ptr().write(5);

    five.assume_init()
};

assert_eq!(*five, 5)

impl<T> Rc<[MaybeUninit<T>]>[src]

pub unsafe fn assume_init(self) -> Rc<[T]>[src]

🔬 This is a nightly-only experimental API. (new_uninit)

Converts to Rc<[T]>.

Safety

As with MaybeUninit::assume_init, it is up to the caller to guarantee that the inner value really is in an initialized state. Calling this when the content is not yet fully initialized causes immediate undefined behavior.

Examples

#![feature(new_uninit)]
#![feature(get_mut_unchecked)]

use std::rc::Rc;

let mut values = Rc::<[u32]>::new_uninit_slice(3);

let values = unsafe {
    // Deferred initialization:
    Rc::get_mut_unchecked(&mut values)[0].as_mut_ptr().write(1);
    Rc::get_mut_unchecked(&mut values)[1].as_mut_ptr().write(2);
    Rc::get_mut_unchecked(&mut values)[2].as_mut_ptr().write(3);

    values.assume_init()
};

assert_eq!(*values, [1, 2, 3])

impl<T> Rc<T> where
    T: ?Sized
[src]

pub fn into_raw(this: Rc<T>) -> *const T1.17.0[src]

Consumes the Rc, returning the wrapped pointer.

To avoid a memory leak the pointer must be converted back to an Rc using Rc::from_raw.

Examples

use std::rc::Rc;

let x = Rc::new("hello".to_owned());
let x_ptr = Rc::into_raw(x);
assert_eq!(unsafe { &*x_ptr }, "hello");

pub fn as_ptr(this: &Rc<T>) -> *const T1.45.0[src]

Provides a raw pointer to the data.

The counts are not affected in any way and the Rc is not consumed. The pointer is valid for as long there are strong counts in the Rc.

Examples

use std::rc::Rc;

let x = Rc::new("hello".to_owned());
let y = Rc::clone(&x);
let x_ptr = Rc::as_ptr(&x);
assert_eq!(x_ptr, Rc::as_ptr(&y));
assert_eq!(unsafe { &*x_ptr }, "hello");

pub unsafe fn from_raw(ptr: *const T) -> Rc<T>1.17.0[src]

Constructs an Rc<T> from a raw pointer.

The raw pointer must have been previously returned by a call to Rc<U>::into_raw where U must have the same size and alignment as T. This is trivially true if U is T. Note that if U is not T but has the same size and alignment, this is basically like transmuting references of different types. See mem::transmute for more information on what restrictions apply in this case.

The user of from_raw has to make sure a specific value of T is only dropped once.

This function is unsafe because improper use may lead to memory unsafety, even if the returned Rc<T> is never accessed.

Examples

use std::rc::Rc;

let x = Rc::new("hello".to_owned());
let x_ptr = Rc::into_raw(x);

unsafe {
    // Convert back to an `Rc` to prevent leak.
    let x = Rc::from_raw(x_ptr);
    assert_eq!(&*x, "hello");

    // Further calls to `Rc::from_raw(x_ptr)` would be memory-unsafe.
}

// The memory was freed when `x` went out of scope above, so `x_ptr` is now dangling!

pub fn downgrade(this: &Rc<T>) -> Weak<T>1.4.0[src]

Creates a new Weak pointer to this allocation.

Examples

use std::rc::Rc;

let five = Rc::new(5);

let weak_five = Rc::downgrade(&five);

pub fn weak_count(this: &Rc<T>) -> usize1.15.0[src]

Gets the number of Weak pointers to this allocation.

Examples

use std::rc::Rc;

let five = Rc::new(5);
let _weak_five = Rc::downgrade(&five);

assert_eq!(1, Rc::weak_count(&five));

pub fn strong_count(this: &Rc<T>) -> usize1.15.0[src]

Gets the number of strong (Rc) pointers to this allocation.

Examples

use std::rc::Rc;

let five = Rc::new(5);
let _also_five = Rc::clone(&five);

assert_eq!(2, Rc::strong_count(&five));

pub fn get_mut(this: &mut Rc<T>) -> Option<&mut T>1.4.0[src]

Returns a mutable reference into the given Rc, if there are no other Rc or Weak pointers to the same allocation.

Returns None otherwise, because it is not safe to mutate a shared value.

See also make_mut, which will clone the inner value when there are other pointers.

Examples

use std::rc::Rc;

let mut x = Rc::new(3);
*Rc::get_mut(&mut x).unwrap() = 4;
assert_eq!(*x, 4);

let _y = Rc::clone(&x);
assert!(Rc::get_mut(&mut x).is_none());

pub unsafe fn get_mut_unchecked(this: &mut Rc<T>) -> &mut T

Notable traits for &'_ mut R

impl<'_, R> Read for &'_ mut R where
    R: Read + ?Sized
impl<'_, W> Write for &'_ mut W where
    W: Write + ?Sized
[src]

🔬 This is a nightly-only experimental API. (get_mut_unchecked)

Returns a mutable reference into the given Rc, without any check.

See also get_mut, which is safe and does appropriate checks.

Safety

Any other Rc or Weak pointers to the same allocation must not be dereferenced for the duration of the returned borrow. This is trivially the case if no such pointers exist, for example immediately after Rc::new.

Examples

#![feature(get_mut_unchecked)]

use std::rc::Rc;

let mut x = Rc::new(String::new());
unsafe {
    Rc::get_mut_unchecked(&mut x).push_str("foo")
}
assert_eq!(*x, "foo");

pub fn ptr_eq(this: &Rc<T>, other: &Rc<T>) -> bool1.17.0[src]

Returns true if the two Rcs point to the same allocation (in a vein similar to ptr::eq).

Examples

use std::rc::Rc;

let five = Rc::new(5);
let same_five = Rc::clone(&five);
let other_five = Rc::new(5);

assert!(Rc::ptr_eq(&five, &same_five));
assert!(!Rc::ptr_eq(&five, &other_five));

impl<T> Rc<T> where
    T: Clone
[src]

pub fn make_mut(this: &mut Rc<T>) -> &mut T

Notable traits for &'_ mut R

impl<'_, R> Read for &'_ mut R where
    R: Read + ?Sized
impl<'_, W> Write for &'_ mut W where
    W: Write + ?Sized
1.4.0[src]

Makes a mutable reference into the given Rc.

If there are other Rc pointers to the same allocation, then make_mut will clone the inner value to a new allocation to ensure unique ownership. This is also referred to as clone-on-write.

If there are no other Rc pointers to this allocation, then Weak pointers to this allocation will be disassociated.

See also get_mut, which will fail rather than cloning.

Examples

use std::rc::Rc;

let mut data = Rc::new(5);

*Rc::make_mut(&mut data) += 1;        // Won't clone anything
let mut other_data = Rc::clone(&data);    // Won't clone inner data
*Rc::make_mut(&mut data) += 1;        // Clones inner data
*Rc::make_mut(&mut data) += 1;        // Won't clone anything
*Rc::make_mut(&mut other_data) *= 2;  // Won't clone anything

// Now `data` and `other_data` point to different allocations.
assert_eq!(*data, 8);
assert_eq!(*other_data, 12);

Weak pointers will be disassociated:

use std::rc::Rc;

let mut data = Rc::new(75);
let weak = Rc::downgrade(&data);

assert!(75 == *data);
assert!(75 == *weak.upgrade().unwrap());

*Rc::make_mut(&mut data) += 1;

assert!(76 == *data);
assert!(weak.upgrade().is_none());

impl Rc<dyn Any + 'static>[src]

pub fn downcast<T>(self) -> Result<Rc<T>, Rc<dyn Any + 'static>> where
    T: Any
1.29.0[src]

Attempt to downcast the Rc<dyn Any> to a concrete type.

Examples

use std::any::Any;
use std::rc::Rc;

fn print_if_string(value: Rc<dyn Any>) {
    if let Ok(string) = value.downcast::<String>() {
        println!("String ({}): {}", string.len(), string);
    }
}

let my_string = "Hello World".to_string();
print_if_string(Rc::new(my_string));
print_if_string(Rc::new(0i8));

[src]

impl<T> Drop for Rc<T> where
    T: ?Sized
[src]

pub fn drop(&mut self)[src]

Drops the Rc.

This will decrement the strong reference count. If the strong reference count reaches zero then the only other references (if any) are Weak, so we drop the inner value.

Examples

use std::rc::Rc;

struct Foo;

impl Drop for Foo {
    fn drop(&mut self) {
        println!("dropped!");
    }
}

let foo  = Rc::new(Foo);
let foo2 = Rc::clone(&foo);

drop(foo);    // Doesn't print anything
drop(foo2);   // Prints "dropped!"

    I: IntoIterator<Item = T>, 
[src]

Takes each element in the Iterator and collects it into an Rc<[T]>.

Performance characteristics

The general case

In the general case, collecting into Rc<[T]> is done by first collecting into a Vec<T>. That is, when writing the following:

let evens: Rc<[u8]> = (0..10).filter(|&x| x % 2 == 0).collect();

this behaves as if we wrote:

let evens: Rc<[u8]> = (0..10).filter(|&x| x % 2 == 0)
    .collect::<Vec<_>>() // The first set of allocations happens here.
    .into(); // A second allocation for `Rc<[T]>` happens here.

This will allocate as many times as needed for constructing the Vec<T> and then it will allocate once for turning the Vec<T> into the Rc<[T]>.

Iterators of known length

When your Iterator implements TrustedLen and is of an exact size, a single allocation will be made for the Rc<[T]>. For example:

let evens: Rc<[u8]> = (0..10).collect(); // Just a single allocation happens here.

impl<T> Hash for Rc<T> where
    T: Hash + ?Sized
[src]

impl<T> Ord for Rc<T> where
    T: Ord + ?Sized
[src]

pub fn cmp(&self, other: &Rc<T>) -> Ordering[src]

Comparison for two Rcs.

The two are compared by calling cmp() on their inner values.

Examples

use std::rc::Rc;
use std::cmp::Ordering;

let five = Rc::new(5);

assert_eq!(Ordering::Less, five.cmp(&Rc::new(6)));

impl<T> PartialEq<Rc<T>> for Rc<T> where
    T: PartialEq<T> + ?Sized
[src]

pub fn eq(&self, other: &Rc<T>) -> bool[src]

Equality for two Rcs.

Two Rcs are equal if their inner values are equal, even if they are stored in different allocation.

If T also implements Eq (implying reflexivity of equality), two Rcs that point to the same allocation are always equal.

Examples

use std::rc::Rc;

let five = Rc::new(5);

assert!(five == Rc::new(5));

pub fn ne(&self, other: &Rc<T>) -> bool[src]

Inequality for two Rcs.

Two Rcs are unequal if their inner values are unequal.

If T also implements Eq (implying reflexivity of equality), two Rcs that point to the same allocation are never unequal.

Examples

use std::rc::Rc;

let five = Rc::new(5);

assert!(five != Rc::new(6));

impl<T> PartialOrd<Rc<T>> for Rc<T> where
    T: PartialOrd<T> + ?Sized
[src]

pub fn partial_cmp(&self, other: &Rc<T>) -> Option<Ordering>[src]

Partial comparison for two Rcs.

The two are compared by calling partial_cmp() on their inner values.

Examples

use std::rc::Rc;
use std::cmp::Ordering;

let five = Rc::new(5);

assert_eq!(Some(Ordering::Less), five.partial_cmp(&Rc::new(6)));

pub fn lt(&self, other: &Rc<T>) -> bool[src]

Less-than comparison for two Rcs.

The two are compared by calling < on their inner values.

Examples

use std::rc::Rc;

let five = Rc::new(5);

assert!(five < Rc::new(6));

pub fn le(&self, other: &Rc<T>) -> bool[src]

‘Less than or equal to’ comparison for two Rcs.

The two are compared by calling <= on their inner values.

Examples

use std::rc::Rc;

let five = Rc::new(5);

assert!(five <= Rc::new(5));

pub fn gt(&self, other: &Rc<T>) -> bool[src]

Greater-than comparison for two Rcs.

The two are compared by calling > on their inner values.

Examples

let five = Rc::new(5);

assert!(five > Rc::new(4));

pub fn ge(&self, other: &Rc<T>) -> bool[src]

‘Greater than or equal to’ comparison for two Rcs.
