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

Methods from Deref<Target = [u8; N]>§
Sourcepub fn as_ascii(&self) -> Option<&[AsciiChar; N]>
🔬This is a nightly-only experimental API. (ascii_char
)
pub fn as_ascii(&self) -> Option<&[AsciiChar; N]>
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");
Sourcepub unsafe fn as_ascii_unchecked(&self) -> &[AsciiChar; N]
🔬This is a nightly-only experimental API. (ascii_char
)
pub unsafe fn as_ascii_unchecked(&self) -> &[AsciiChar; N]
ascii_char
)Converts this array of bytes into an array of ASCII characters, without checking whether they’re valid.

, or else this is UB.
1.57.0 · Sourcepub fn as_slice(&self) -> &[T]
pub fn as_slice(&self) -> &[T]
Returns a slice containing the entire array. Equivalent to &s[..]
.
1.57.0 · Sourcepub fn as_mut_slice(&mut self) -> &mut [T]
pub fn as_mut_slice(&mut self) -> &mut [T]

&mut s[..]
.
1.77.0 · Sourcepub fn each_ref(&self) -> [&T; N]
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();

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]);

assert_eq!(strings.len(), 3);

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]);
