Function winnow::character::alphanumeric0
source · pub fn alphanumeric0<I, E: ParseError<I>>(
input: I
) -> IResult<I, <I as Stream>::Slice, E>where
I: StreamIsPartial + Stream,
<I as Stream>::Token: AsChar,
Expand description
Recognizes zero or more ASCII numerical and alphabetic characters: 0-9, a-z, A-Z
Complete version: Will return the whole input if no terminating token is found (a non alphanumerical character).
Partial version: Will return Err(winnow::error::ErrMode::Incomplete(_))
if there’s not enough input data,
or if no terminating token is found (a non alphanumerical character).
Example
fn parser(input: &str) -> IResult<&str, &str> {
alphanumeric0(input)
}
assert_eq!(parser("21cZ%1"), Ok(("%1", "21cZ")));
assert_eq!(parser("&Z21c"), Ok(("&Z21c", "")));
assert_eq!(parser(""), Ok(("", "")));
assert_eq!(alphanumeric0::<_, Error<_>>(Partial::new("21cZ%1")), Ok((Partial::new("%1"), "21cZ")));
assert_eq!(alphanumeric0::<_, Error<_>>(Partial::new("&Z21c")), Ok((Partial::new("&Z21c"), "")));
assert_eq!(alphanumeric0::<_, Error<_>>(Partial::new("")), Err(ErrMode::Incomplete(Needed::new(1))));
