Function nom::number::complete::le_i64

pub fn le_i64<I, E: ParseError<I>>(input: I) -> IResult<I, i64, E>where
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength,

Recognizes a little endian signed 8 bytes integer.

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