pub fn hex_decode_array_with_case<const N: usize>(
src: &[u8],
check_case: CheckCase,
) -> Result<[u8; N], Error>Expand description
Decodes exactly N bytes into an array using an explicit letter-case policy.
This has the ownership, exact-length and allocation-free guarantees of
hex_decode_array. Only N == 0 accepts empty input.
§Errors
Returns Error::OddLength, Error::LengthMismatch, then
Error::InvalidChar in that order. A disallowed letter case is an invalid
character. Mismatched lengths count decoded bytes; invalid-character indexes
count source bytes.
§Examples
use faster_hex::{hex_decode_array_with_case, CheckCase};
let id = hex_decode_array_with_case::<2>(b"AB01", CheckCase::Upper)?;
assert_eq!(id, [0xab, 1]);
assert!(hex_decode_array_with_case::<2>(b"ab01", CheckCase::Upper).is_err());
