Function winnow::number::le_u128

source ·
pub fn le_u128<I, E: ParseError<I>>(input: I) -> IResult<I, u128, E>where
    I: StreamIsPartial + Stream<Token = u8>,
    <I as Stream>::Slice: AsBytes,
Expand description

Recognizes a little endian unsigned 16 bytes integer.

Complete version: Returns an error if there is not enough input data.

Partial version: Will return Err(winnow::error::ErrMode::Incomplete(_)) if there is not enough data.

Example

use winnow::number::le_u128;

let parser = |s| {
  le_u128(s)
};

assert_eq!(parser(&b"\x00\x01\x02\x03\x04\x05\x06\x07\x00\x01\x02\x03\x04\x05\x06\x07abcefg"[..]), Ok((&b"abcefg"[..], 0x07060504030201000706050403020100)));

use winnow::number::le_u128;
