Struct bevy_reflect::TypeRegistration
source · 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
impl TypeRegistration
sourcepub fn data<T: TypeData>(&self) -> Option<&T>
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.
sourcepub fn data_mut<T: TypeData>(&mut self) -> Option<&mut T>
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.
sourcepub fn type_info(&self) -> &'static TypeInfo
pub fn type_info(&self) -> &'static TypeInfo
Returns a reference to the registration’s TypeInfo
