pub struct CharULE(/* private fields */);
Expand description
A u8 array of little-endian data corresponding to a Unicode scalar value.
The bytes of a CharULE
are guaranteed to represent a little-endian-encoded u32 that is a
valid char
and can be converted without validation.
§Examples
Convert a char
to a CharULE
and back again:
use zerovec::ule::{AsULE, CharULE, ULE};
let c1 = '𑄃';
let ule = c1.to_unaligned();
assert_eq!(CharULE::as_byte_slice(&[ule]), &[0x03, 0x11, 0x01]);
let c2 = char::from_unaligned(ule);
assert_eq!(c1, c2);
Attempt to parse invalid bytes to a CharULE
:
use zerovec::ule::{CharULE, ULE};
let bytes: &[u8] = &[0xFF, 0xFF, 0xFF, 0xFF];
CharULE::parse_byte_slice(bytes).expect_err("Invalid bytes");
Implementations§
source§impl CharULE
impl CharULE
sourcepub const fn from_aligned(c: char) -> Self
pub const fn from_aligned(c: char) -> Self
Converts a char
to a CharULE
. This is equivalent to calling
AsULE::to_unaligned()
See the type-level documentation for CharULE
for more information.
