const_hex

Function const_check

Source
pub const fn const_check(input: &[u8]) -> Result<(), FromHexError>
Expand description

Returns true if the input is a valid hex string and can be decoded successfully.

Prefer using check instead when possible (at runtime), as it is likely to be faster.

    assert!(const_hex::const_check(b"0x48656c6c6f20776f726c6421").is_ok());

    assert!(const_hex::const_check(b"48656c6c6f20776f726c642").is_err());
    assert!(const_hex::const_check(b"Hello world!").is_err());
