Implementations
impl StakeHistory
[src]
pub fn get(&self, epoch: &u64) -> Option<&StakeHistoryEntry>
[src]
pub fn add(&mut self, epoch: u64, entry: StakeHistoryEntry)
[src]
Methods from Deref<Target = Vec<(u64, StakeHistoryEntry), Global>>
pub fn capacity(&self) -> usize
1.0.0[src]
Returns the number of elements the vector can hold without reallocating.
Examples
let vec: Vec<i32> = Vec::with_capacity(10); assert_eq!(vec.capacity(), 10);
pub fn as_slice(&self) -> &[T]
1.7.0[src]
Extracts a slice containing the entire vector.
Equivalent to &s[..]
.
Examples
use std::io::{self, Write}; let buffer = vec![1, 2, 3, 5, 8]; io::sink().write(buffer.as_slice()).unwrap();
pub fn as_ptr(&self) -> *const T
1.37.0[src]
Returns a raw pointer to the vector’s buffer.
The caller must ensure that the vector outlives the pointer this function returns, or else it will end up pointing to garbage. Modifying the vector may cause its buffer to be reallocated, which would also make any pointers to it invalid.
The caller must also ensure that the memory the pointer (non-transitively) points to
is never written to (except inside an UnsafeCell
) using this pointer or any pointer
derived from it. If you need to mutate the contents of the slice, use as_mut_ptr
.
Examples
let x = vec![1, 2, 4]; let x_ptr = x.as_ptr(); unsafe { for i in 0..x.len() { assert_eq!(*x_ptr.add(i), 1 << i); } }
pub fn allocator(&self) -> &A
[src]
allocator_api
)Returns a reference to the underlying allocator.
pub fn len(&self) -> usize
1.0.0[src]
Returns the number of elements in the vector, also referred to as its ‘length’.
Examples
let a = vec![1, 2, 3]; assert_eq!(a.len(), 3);
pub fn is_empty(&self) -> bool
1.0.0[src]
Returns true
if the vector contains no elements.
Examples
let mut v = Vec::new(); assert!(v.is_empty()); v.push(1); assert!(!v.is_empty());
