Function chomp::combinators::many_till [−] [src]

pub fn many_till<I: Input, T, E, R, F, U, N, V>(
    i: I, 
    p: R, 
    end: F
) -> ParseResult<I, T, E> where
    T: FromIterator<U>,
    E: From<N>,
    R: FnMut(I) -> ParseResult<I, U, E>,
    F: FnMut(I) -> ParseResult<I, V, N>,

Applies the parser R multiple times until the parser F succeeds and returns a T: FromIterator populated by the values yielded by R. Consumes the matched part of F.

This parser is considered incomplete if the parser R is considered incomplete.

Errors from R are propagated.
