pub struct TypeRegistration { /* private fields */ }
Expand description

Runtime storage for type metadata, registered into the TypeRegistry.

An instance of TypeRegistration can be created using the TypeRegistration::of method, but is more often automatically generated using #[derive(Reflect)] which itself generates an implementation of the GetTypeRegistration trait.

Along with the type’s TypeInfo, this struct also contains a type’s registered TypeData.

See the crate-level documentation for more information on type registration.

Example

let mut registration = TypeRegistration::of::<Option<String>>();

assert_eq!("core::option::Option<alloc::string::String>", registration.type_info().type_path());
assert_eq!("Option<String>", registration.type_info().type_path_table().short_path());

registration.insert::<ReflectDefault>(FromType::<Option<String>>::from_type());
assert!(registration.data::<ReflectDefault>().is_some())

Implementations§

source§

impl TypeRegistration

source

pub fn type_id(&self) -> TypeId

Returns the TypeId of the type.

source

pub fn data<T: TypeData>(&self) -> Option<&T>

Returns a reference to the value of type T in this registration’s type data.

Returns None if no such value exists.

source

pub fn data_mut<T: TypeData>(&mut self) -> Option<&mut T>

Returns a mutable reference to the value of type T in this registration’s type data.

Returns None if no such value exists.

source

pub fn type_info(&self) -> &'static TypeInfo

Returns a reference to the registration’s TypeInfo

source

pub fn insert<T: TypeData>(&mut self, data: T)

Inserts an instance of T into this registration’s type data.

If another instance of T was previously inserted, it is replaced.

source

pub fn of<T: Reflect + Typed + TypePath>() -> Self

Creates type registration information for T.
