Struct pwasm_std::hash::H32

#[repr(C)]
pub struct H32(pub [u8; 4]);

Unformatted binary data of fixed length.

Methods

impl H32

fn new() -> H32

Create a new, zero-initialised, instance.

fn zero() -> H32

Synonym for new(). Prefer to new as it's more readable.

fn len() -> usize

Get the size of this object in bytes.

fn as_ptr(&self) -> *const u8

Returns a constant raw pointer to the value

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

Returns a mutable raw pointer to the value

fn clone_from_slice(&mut self, src: &[u8]) -> usize

Assign self to be of the same value as a slice of bytes of length len().

fn from_slice(src: &[u8]) -> H32

Convert a slice of bytes of length len() to an instance of this type.

fn copy_to(&self, dest: &mut [u8])

Copy the data of this object into some mutable slice of length len().

fn contains(&'a self, b: &'a H32) -> bool

Returns true if all bits set in b are also set in self.

fn is_zero(&self) -> bool

Returns true if no bits are set.

fn low_u64(&self) -> u64

Returns the lowest 8 bytes interpreted as a BigEndian integer.
