Enum CheckCase 

pub enum CheckCase {
    None,
    Lower,
    Upper,
}

Which ASCII letter cases are accepted when checking or decoding hex.

None is the default and accepts mixed case; it does not disable character validation. All policies accept ASCII digits 0 through 9 and reject prefixes, whitespace and non-ASCII characters. They do not change the length rules of the operation using them.

Encoding selects lowercase or uppercase through separate functions, so an encoding operation never needs this policy.

Examples

use faster_hex::{hex_decode_with_case, CheckCase};

let mut bytes = [0; 2];
assert_eq!(hex_decode_with_case(b"AB01", &mut bytes, CheckCase::Upper)?,
           &[0xab, 1]);
assert!(hex_decode_with_case(b"ab01", &mut bytes, CheckCase::Upper).is_err());

Variants

None

Accept uppercase and lowercase, including a mixture of both.

Lower

Accept digits and lowercase a through f only.

Upper

Accept digits and uppercase A through F only.
