Function le_u8

Source
pub fn le_u8<I, E: ParseError<I>>(input: I) -> IResult<I, u8, E>
where I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength,
Expand description

Recognizes an unsigned 1 byte integer.

Streaming version: Will return Err(nom::Err::Incomplete(_)) if there is not enough data.

use nom::number::streaming::le_u8;

let parser = le_u8::<_, (_, ErrorKind)>;

assert_eq!(parser(&b"\x00\x01abcd"[..]), Ok((&b"\x01abcd"[..], 0x00)));
assert_eq!(parser(&b""[..]), Err(Err::Incomplete(Needed::new(1))));
