Function nom::number::streaming::le_i32[−][src]

pub fn le_i32<I, E: ParseError<I>>(input: I) -> IResult<I, i32, E> where
    I: Slice<RangeFrom<usize>> + InputIter<Item = u8> + InputLength,

Recognizes a little endian signed 4 bytes integer.

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