Function `separated_list0`

fn separated_list0<I, E, F, G>(sep: G, f: F) -> impl Parser<I, Output = crate::lib::std::vec::Vec<<F as Parser<I>>::Output>, Error = E>
where
    I: Clone + Input,
    F: Parser<I, Error = E>,
    G: Parser<I, Error = E>,
    E: ParseError<I>

Alternates between two parsers to produce a list of elements.

This stops when either parser returns Err::Error and returns the results that were accumulated. To instead chain an error up, see [cut][crate::combinator::cut].

Arguments

sep Parses the separator between list elements.
f Parses the elements of the list.
