Expand description
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![], "")));
