👎Deprecated since 8.0.0: Replaced with nom8::character::hex_digit0 with input wrapped in nom8::input::Streaming
Expand description

Recognizes zero or more ASCII hexadecimal numerical characters: 0-9, A-F, a-f

Streaming version: Will return Err(nom8::Err::Incomplete(_)) if there’s not enough input data, or if no terminating token is found (a non hexadecimal digit character).

Example

assert_eq!(hex_digit0::<_, (_, ErrorKind)>("21cZ"), Ok(("Z", "21c")));
assert_eq!(hex_digit0::<_, (_, ErrorKind)>("Z21c"), Ok(("Z21c", "")));
assert_eq!(hex_digit0::<_, (_, ErrorKind)>(""), Err(Err::Incomplete(Needed::new(1))));

WARNING: Deprecated, replaced with nom8::character::hex_digit0 with input wrapped in nom8::input::Streaming
