Function nom::anychar

pub fn anychar<T>(input: T) -> IResult<T, char> where
    T: InputIter + InputLength + Slice<RangeFrom<usize>> + AtEof,
    <T as InputIter>::Item: AsChar, 

matches one byte as a character. Note that the input type will accept a str, but not a &[u8], unlike many other nom parsers.

Example

assert_eq!(anychar("abc"), Ok(("bc",'a')));
