pub fn le_i24<Input, Error>(input: &mut Input) -> Result<i32, Error>
Expand description
Recognizes a little endian signed 3 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::le_i24;
fn parser(s: &mut &[u8]) -> ModalResult<i32> {
le_i24.parse_next(s)
}
assert_eq!(parser.parse_peek(&b"\x00\x03\x05abcefg"[..]), Ok((&b"abcefg"[..], 0x050300)));
assert!(parser.parse_peek(&b"\x01"[..]).is_err());
use winnow::binary::le_i24;
fn parser(s: &mut Partial<&[u8]>) -> ModalResult<i32> {
le_i24.parse_next(s)
}
assert_eq!(parser.parse_peek(Partial::new(&b"\x00\x01\x02abcd"[..])), Ok((Partial::new(&b"abcd"[..]), 0x020100)));
assert_eq!(parser.parse_peek(Partial::new(&b"\x01"[..])), Err(ErrMode::Incomplete(Needed::new(2))));
