Trait for mapping a class struct type to its corresponding instance type.

Associated Types

`type Instance: ObjectType`[−]

Corresponding Rust instance type for this class.

Provided methods

`fn get_type(&self) -> Type`[−]

Get the type id for this class.

`fn upcast_ref<U>(&self) -> &U where U: IsClassFor, Self::Instance: IsA<<U as IsClassFor>::Instance>, <U as IsClassFor>::Instance: ObjectType,` [−]

Casts this class to a reference to a parent type's class.

`fn upcast_ref_mut<U>(&mut self) -> &mut U where U: IsClassFor, Self::Instance: IsA<<U as IsClassFor>::Instance>, <U as IsClassFor>::Instance: ObjectType,` [−]

Casts this class to a mutable reference to a parent type's class.

`fn downcast_ref<U>(&self) -> Option<&U> where U: IsClassFor, <U as IsClassFor>::Instance: IsA<Self::Instance>, Self::Instance: ObjectType,` [−]

Casts this class to a reference to a child type's class or fails if this class is not implementing the child class.

`fn downcast_ref_mut<U>(&mut self) -> Option<&mut U> where U: IsClassFor, <U as IsClassFor>::Instance: IsA<Self::Instance>, Self::Instance: ObjectType,` [−]

Casts this class to a mutable reference to a child type's class or fails if this class is not implementing the child class.

`fn from_type(type_: Type) -> Option<ClassRef<Self>>`[−]

Search Tricks

Prefix searches with a type followed by a colon (e.g., fn:) to restrict the search to a given type.

Accepted types are: fn, mod, struct, enum, trait, type, macro, and const.

Search functions by type signature (e.g., vec -> usize or * -> vec)

Search multiple things at once by splitting your query with comma (e.g., str,u8 or String,struct:Vec,test)

You can look for items with an exact name by putting double quotes around your request: "string"

Look for items inside another one by searching for a path: vec::Vec
