Struct 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: FixedBytes<N> = _

Array of Zero bytes.

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

Wraps the given byte array in FixedBytes.

pub const fn with_last_byte(x: u8) -> FixedBytes<N>

pub const fn concat_const<const M: usize, const Z: usize>( self, other: FixedBytes<M>, ) -> FixedBytes<Z>

Panics

If the length of src and the number of bytes in Self do not match.

pub fn left_padding_from(value: &[u8]) -> FixedBytes<N>

Create a new FixedBytes from the given slice src, left-padding it with zeroes if necessary.

Note

The given bytes are interpreted in big endian order.

Panics

Panics if src.len() > N.

pub fn right_padding_from(value: &[u8]) -> FixedBytes<N>

Create a new FixedBytes from the given slice src, right-padding it with zeroes if necessary.

Note

The given bytes are interpreted in big endian order.

Panics

Panics if src.len() > N.

Methods from Deref<Target = [u8; N]>

pub fn as_ascii(&self) -> Option<&[AsciiChar; N]>

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

Converts this array of bytes into an array of ASCII characters, or returns None if any of the characters is non-ASCII.

Examples

#![feature(ascii_char)]

const HEX_DIGITS: [std::ascii::Char; 16] =
    *b"0123456789abcdef".as_ascii().unwrap();

assert_eq!(HEX_DIGITS[1].as_str(), "1");
assert_eq!(HEX_DIGITS[10].as_str(), "a");

pub unsafe fn as_ascii_unchecked(&self) -> &[AsciiChar; N]

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

Converts this array of bytes into an array of ASCII characters, without checking whether they’re valid.

Safety

Every byte in the array must be in 0..=127, or else this is UB.

pub fn as_slice(&self) -> &[T]

Returns a slice containing the entire array. Equivalent to &s[..].

pub fn as_mut_slice(&mut self) -> &mut [T]

Returns a mutable slice containing the entire array. Equivalent to &mut s[..].

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

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

Example

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.

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

// 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]

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

Example

let mut floats = [3.1, 2.7, -1.0];
let float_refs: [&mut f64; 3] = floats.each_mut();
*float_refs[0] = 0.0;
assert_eq!(float_refs, [&mut 0.0, &mut 2.7, &mut -1.0]);
assert_eq!(floats, [0.0, 2.7, -1.0]);

pub fn split_array_ref<const M: usize>(&self) -> (&[T; M], &[T])

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

Divides one array reference into two at an index.

The first will contain all indices from [0, M) (excluding the index M itself) and the second will contain all indices from [M, N) (excluding the index N itself).

Panics

Panics if M > N.

let v = [1, 2, 3, 4, 5, 6];

{
   let (left, right) = v.split_array_ref::<0>();

    assert_eq!(left, &[1, 2, 3, 4, 5, 6]);
    assert_eq!(right, &[]);
}

pub fn split_array_mut<const M: usize>(&mut self) -> (&mut [T; M], &mut [T])

let mut v = [1, 0, 3, 0, 5, 6];
let (left, right) = v.split_array_mut::<2>();
assert_eq!(left, &mut [1, 0][..]);

assert_eq!(v, [1, 2, 3, 4, 5, 6]);

pub fn rsplit_array_ref<const M: usize>(&self) -> (&[T], &[T; M])

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

Divides one array reference into two at an index from the end.

The first will contain all indices from [0, N - M) (excluding the index N - M itself) and the second will contain all indices from [N - M, N) (excluding the index N itself).

Panics

Panics if M > N.

Examples

#![feature(split_array)]

let v = [1, 2, 3, 4, 5, 6];
