Function nom::sequence::terminated

pub fn terminated<I, O1, O2, E: ParseError<I>, F, G>(
    first: F,
    second: G,
) -> impl FnMut(I) -> IResult<I, O1, E>
where
    F: Parser<I, O1, E>,
    G: Parser<I, O2, E>,

Gets an object from the first parser, then matches an object from the second parser and discards it.

Arguments

• first The first parser to apply.
• second The second parser to match an object.
