Macro js_serializable

macro_rules! js_serializable {
    ($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 pass an instance of a given type implementing Serde’s Serialize into the js! macro.

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

Examples

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

js_serializable!( Person );

let person = Person {
   name: "Bob".to_owned(),
   age: 33
};

js! {
    var person = @{person};
    console.log( person.name + " is " + person.age + " years old." );
};

This macro also accepts generics:

trait Foobar {}

#[derive(Serialize)]
struct Wrapper< 'a, T: Serialize + 'a >( &'a T );

js_serializable!( impl< 'a, T > for Wrapper< 'a, T > where T: Serialize + Foobar );
