Implementations

impl Signature

pub fn new() -> Signature

Create a new (zeroed) signature usable for the FFI interface

pub unsafe fn blank() -> Signature

👎 Deprecated since 0.15.3:

Please use the new function instead

Create a new (uninitialized) signature usable for the FFI interface

impl Signature

pub fn as_ptr(&self) -> *const u8

Converts the object to a raw pointer for FFI interfacing

pub fn as_mut_ptr(&mut self) -> *mut u8

Converts the object to a mutable raw pointer for FFI interfacing

pub fn as_ref(&self) -> &[u8; 64]

Gets a reference to the underlying array

pub fn len(&self) -> usize

Returns the length of the object as an array

pub fn is_empty(&self) -> bool

Returns whether the object as an array is empty

impl Ord for Signature

pub fn cmp(&self, other: &Signature) -> Ordering

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.
