Function nom::number::streaming::be_u128

pub fn be_u128<I, E: ParseError<I>>(input: I) -> IResult<I, u128, E>where
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength,

Recognizes a big endian unsigned 16 bytes integer.

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