Function winnow::number::be_i128

pub fn be_i128<I, E: ParseError<I>>(input: I) -> IResult<I, i128, E>where
    I: StreamIsPartial + Stream<Token = u8>,
    <I as Stream>::Slice: AsBytes,

Recognizes a big endian signed 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::be_i128;

let parser = |s| {
  be_i128(s)
