Struct AnyDynMetadata

pub struct AnyDynMetadata(/* private fields */);

An untyped metadata that corresponds to the metadata that would be used for a trait object.

Implementations

impl AnyDynMetadata

pub const fn upcast<T: ?Sized>(meta: DynMetadata<T>) -> AnyDynMetadata

Upcasts this typed metadata into untyped metadata.

pub const unsafe fn downcast<T: DynDynCastTarget + ?Sized>( self, ) -> DynMetadata<T>

Downcasts this untyped metadata into typed metadata for a trait object referring to a particular trait.

Safety

This untyped metadata must have originally been constructed by converting a DynMetadata<T>.
