pub fn be_i128<Input, Error>(input: &mut Input) -> PResult<i128, Error>where
Input: StreamIsPartial + Stream<Token = u8>,
<Input as Stream>::Slice: AsBytes,
Error: ParserError<Input>,
Expand description
Recognizes a big 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.
