Trait parsell::UncommittedStr

pub trait UncommittedStr<'a>: UncommittedInfer<char, Chars<'a>> {
    fn init_str(
        &self, 
        string: &'a str
    ) -> Option<ParseResult<Self::State, Self::Output>>
    where
        Self: Sized,
    { ... }
}

A trait for uncommitted string parsers.

Provided Methods

fn init_str(
    &self,
    string: &'a str
) -> Option<ParseResult<Self::State, Self::Output>> where
    Self: Sized, 

Provides string data to the parser.

If parser: UncommittedInfer<char, Chars<'a>> and data: &'a str, then parser.init_str(data) is short-hand for parser.init(&mut data.chars()).

For example:

let parser = character(char::is_alphabetic).star(String::new);
match parser.init_str("ab").unwrap() {
    Continue(stateful) => match stateful.more_str("cd") {
        Continue(stateful) => match stateful.more_str("ef!") {
            Done(result) => assert_eq!(result, "abcdef"),
            _ => panic!("can't happen"),
        },
        _ => panic!("can't happen"),
    },
    _ => panic!("can't happen"),
}
