Function nom8::character::multispace1
source · pub fn multispace1<T, E: ParseError<T>, const STREAMING: bool>(
input: T
) -> IResult<T, <T as IntoOutput>::Output, E>where
T: InputTakeAtPosition + InputIsStreaming<STREAMING> + IntoOutput,
<T as InputTakeAtPosition>::Item: AsChar + Clone,
Expand description
Recognizes one or more spaces, tabs, carriage returns and line feeds.
Complete version: will return an error if there’s not enough input data, or the whole input if no terminating token is found (a non space character).
Streaming version: Will return Err(nom8::Err::Incomplete(_))
if there’s not enough input data,
or if no terminating token is found (a non space character).
Example
fn parser(input: &str) -> IResult<&str, &str> {
multispace1(input)
}
assert_eq!(parser(" \t\n\r21c"), Ok(("21c", " \t\n\r")));
assert_eq!(parser("H2"), Err(Err::Error(Error::new("H2", ErrorKind::MultiSpace))));
assert_eq!(parser(""), Err(Err::Error(Error::new("", ErrorKind::MultiSpace))));
assert_eq!(multispace1::<_, (_, ErrorKind), true>(Streaming(" \t\n\r21c")), Ok((Streaming("21c"), " \t\n\r")));
assert_eq!(multispace1::<_, (_, ErrorKind), true>(Streaming("H2")), Err(Err::Error((Streaming("H2"), ErrorKind::MultiSpace))));
assert_eq!(multispace1::<_, (_, ErrorKind), true>(Streaming("")), Err(Err::Incomplete(Needed::new(1))));
