nom-fields

This crate provides a single function-like macro that removes some boilerplate from a common pattern when using the parsing framework nom.

With this macro, the following parser...

nom::combinator::map(
    nom::sequence::tuple((
        some_parser,
        some_other_parser,
        a_third_parser
    )),
    |(some_field, some_other_field, a_third_field)| SomeStruct {
        some_field,
        some_other_field,
        a_third_field
    }
)(input)

...becomes this:

nom_fields::fields!(SomeStruct:
    some_field = some_parser,
    some_other_field = some_other_parser,
    a_third_field = a_third_parser
)(input)
