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.easy_parse(position::Stream::new("1,2,3"))
.map(|(vec, state)| (vec, state.input));
assert_eq!(result_ok, Ok((vec!['1', '2', '3'], "")));

position: SourcePosition::default(),
errors: vec![
easy::Error::end_of_input(),
easy::Error::Expected("digit".into())
