Struct alloy_primitives::FixedBytes

#[repr(transparent)]
pub struct FixedBytes<const N: usize>(pub [u8; N]);

A byte array of fixed length ([u8; N]).

This type allows us to more tightly control serialization, deserialization. rlp encoding, decoding, and other type-level attributes for fixed-length byte arrays.

Users looking to prevent type-confusion between byte arrays of different lengths should use the wrap_fixed_bytes! macro to create a new fixed-length byte array type.

Tuple Fields

0: [u8; N]

Implementations

impl<const N: usize> FixedBytes<N>

pub const ZERO: Self = _

Array of Zero bytes.

pub const fn new(bytes: [u8; N]) -> Self

pub fn each_ref(&self) -> [&T; N]

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

Borrows each element and returns an array of references with the same size as self.

Example

#![feature(array_methods)]

let floats = [3.1, 2.7, -1.0];
let float_refs: [&f64; 3] = floats.each_ref();
assert_eq!(float_refs, [&3.1, &2.7, &-1.0]);

This method is particularly useful if combined with other methods, like map. This way, you can avoid moving the original array if its elements are not Copy.

#![feature(array_methods)]

let strings = ["Ferris".to_string(), "♥".to_string(), "Rust".to_string()];
let is_ascii = strings.each_ref().map(|s| s.is_ascii());

// We can still access the original array: it has not been moved.
assert_eq!(strings.len(), 3);

pub fn each_mut(&mut self) -> [&mut T; N]

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