Function nom8::number::u128

pub fn u128<I, E: ParseError<I>, const STREAMING: bool>(
    endian: Endianness
) -> fn(_: I) -> IResult<I, u128, E>where
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength + InputIsStreaming<STREAMING>,

Recognizes an unsigned 16 byte integer

If the parameter is nom8::number::Endianness::Big, parse a big endian u128 integer, otherwise if nom8::number::Endianness::Little parse a little endian u128 integer.

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

Streaming version: Will return Err(nom8::Err::Incomplete(_)) if there is not enough data.

Example
