Function combine::parser::repeat::sep_by

pub fn sep_by<F, P, S>(parser: P, separator: S) -> SepBy<F, P, S> where
    F: Extend<P::Output> + Default,
    P: Parser,
    S: Parser<Input = P::Input>, 

Parses parser zero or more time separated by separator, returning a collection with the values from p.

If the returned collection cannot be inferred type annotations must be supplied, either by annotating the resulting type binding let collection: Vec<_> = ... or by specializing when calling sep_by, sep_by::<Vec<_>, _, _>(...).

let mut parser = sep_by(digit(), token(','));
let result_ok = parser.parse("1,2,3");
assert_eq!(result_ok, Ok((vec!['1', '2', '3'], "")));
let result_ok2 = parser.parse("");
assert_eq!(result_ok2, Ok((vec![], "")));
