[src]
pub fn sep_by1<F, P, S>(parser: P, separator: S) -> SepBy1<F, P, S> where F: FromIterator<P::Output>, P: Parser, S: Parser<Input=P::Input>
Parses parser
one 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_by1::<Vec<_>, _, _>(...)
let mut parser = sep_by1(digit(), token(',')); let result_ok = parser.parse(State::new("1,2,3")) .map(|(vec, state)| (vec, state.input)); assert_eq!(result_ok, Ok((vec!['1', '2', '3'], ""))); let result_err = parser.parse(State::new("")); assert_eq!(result_err, Err(ParseError { position: <char as Positioner>::start(), errors: vec![ Error::end_of_input(), Error::Expected("digit".into()) ] }));
