Macro screeps::macros::js_deserializable

macro_rules! js_deserializable {
    ($ kind : tt) => { ... };
    (impl < $ ($ impl_arg : tt) , * > for $ kind : ty where $ ($ bounds : tt) *) => { ... };
    (impl < $ ($ impl_arg : tt) , * > for $ kind : ty) => { ... };
}

A macro which makes it possible to convert an instance of a given type implementing Serde's Deserialize into a Value using TryInto.

For types defined outside of your crate you can also use the Serde newtype to make them deserializable indirectly.

Examples

#[derive(Deserialize, Debug)]
struct Person {
    name: String,
    age: i32
}

js_deserializable!( Person );

let value = js! {
    return {
        name: "Bob",
        age: 33
    };
};

let structure: Person = value.try_into().unwrap();
assert_eq!( structure.name, "Bob" );
assert_eq!( structure.age, 33 );

This macro also accepts generics just as the js_serializable! does.
