Function separated_list1

pub fn separated_list1<I, E, F, G>(
    separator: G,
    parser: F,
) -> impl Parser<I, Output = 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 until Err::Error.

Fails if the element parser does not produce at least one element.

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

Arguments

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