Trait FromType

Source

    // Provided method
    fn insert_dependencies(_type_registration: &mut TypeRegistration) { ... }
}

Expand description

Trait used to generate TypeData for trait reflection.

This is used by the #[derive(Reflect)] macro to generate an implementation of TypeData to pass to TypeRegistration::insert.

Required Methods§

Source

fn from_type() -> Self

Creates an instance of Self for type T.

Provided Methods§

Source

fn insert_dependencies(_type_registration: &mut TypeRegistration)

Inserts TypeData dependencies of this TypeData. This is especially useful for trait TypeData that has a supertrait (ex: A: B). When the TypeData for A is inserted, the B TypeData will also be inserted.
