pub fn u8<I, E: ParseError<I>>(input: I) -> IResult<I, u8, E>where

👎Deprecated since 0.1.0: Replaced with <code>winnow::number::u8</code> with input wrapped in <code>winnow::Partial</code>
Expand description

Recognizes an unsigned 1 byte integer

Note that endianness does not apply to 1 byte numbers. Partial version: Will return Err(winnow::error::ErrMode::Incomplete(_)) if there is not enough data.

use winnow::number::streaming::u8;

let parser = |s| {
  u8::<_, Error<_>>(s)
};

assert_eq!(parser(&b"\x00\x03abcefg"[..]), Ok((&b"\x03abcefg"[..], 0x00)));
assert_eq!(parser(&b""[..]), Err(ErrMode::Incomplete(Needed::new(1))));
