Macro named_parameters

macro_rules! named_parameters {
    ( $vis:vis $param_name:ident { $($key:ident = $value:ty),* $(,)? }) => { ... };
}

Define a new type that implements ParseArguments

This can then be used in your custom Verb or Condition implementations.

Note: The definition uses = instead of the usual : to delimit fields and their types. This is on purpose, as this may later be expanded to allow for positional arguments as well.

use test_dsl::named_parameters;

named_parameters! {
    Frobnicator {
        foo = usize,
        name = String
    }
}
