pub fn bool<Input, Error: ParserError<(Input, usize)>>(
input: &mut (Input, usize)
) -> PResult<bool, Error>
Expand description
Parses one specific bit as a bool.
Effective Signature
Assuming you are parsing a (&[u8], usize)
bit Stream:
pub fn bool(input: &mut (&[u8], usize)) -> PResult<bool>
Example
use winnow::binary::bits::bool;
type Stream<'i> = &'i Bytes;
fn stream(b: &[u8]) -> Stream<'_> {
Bytes::new(b)
}
fn parse(input: (Stream<'_>, usize)) -> IResult<(Stream<'_>, usize), bool> {
bool.parse_peek(input)
}
assert_eq!(parse((stream(&[0b10000000]), 0)), Ok(((stream(&[0b10000000]), 1), true)));
assert_eq!(parse((stream(&[0b10000000]), 1)), Ok(((stream(&[0b10000000]), 2), false)));
