Function be_u128

pub fn be_u128<Input, Error>(input: &mut Input) -> Result<u128, Error>
where
    Input: StreamIsPartial + Stream<Token = u8>,
    Error: ParserError<Input>,

Recognizes a big endian unsigned 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::be_u128;

fn parser(s: &mut &[u8]) -> ModalResult<u128> {
