Function nom8::sequence::pair

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

👎Deprecated since 8.0.0: Parser is directly implemented for tuples

Gets an object from the first parser, then gets another object from the second parser.

WARNING: Deprecated, Parser is directly implemented for tuples

Arguments
