Function chomp::combinators::many1 [−] [src]

pub fn many1<I: Input, T, E, F, U>(i: I, f: F) -> ParseResult<I, T, E> where
    F: FnMut(I) -> ParseResult<I, U, E>,
    T: FromIterator<U>,

Parses at least one instance of f and continues until it does no longer match, collecting all matches into the type T: FromIterator.

Note: If the last parser succeeds on the last input item then this parser is still considered incomplete as there might be more data to fill.

Note: Allocates data.

use chomp::prelude::{Error, parse_only, token, many1, take_while1};

let p = |i| many1(i, |i| take_while1(i, |c| c != b',' && c != b' ')
            .bind(|i, c| token(i, b',')
                         .map(|_| c)));

assert_eq!(parse_only(&p, b"a "), Err((&b" "[..], Error::expected(b','))));
assert_eq!(parse_only(&p, b"a, "), Ok(vec![&b"a"[..]]));
