Function le_i128

pub fn le_i128<Input, Error>(input: &mut Input) -> PResult<i128, Error>
where
    Input: StreamIsPartial + Stream<Token = u8>,
    Error: ParserError<Input>,

Recognizes a little endian signed 16 bytes integer.

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

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

Example

use winnow::binary::le_i128;

fn parser(s: &[u8]) -> IResult<&[u8], i128> {
