This commit aims to stabilize the `TypeId` abstraction by moving it out of the `intrinsics` module into the `any` module of the standard library. Specifically, * `TypeId` is now defined at `std::any::TypeId` * `TypeId::hash` has been removed in favor of an implementation of `Hash`. This commit also performs a final pass over the `any` module, confirming the following: * `Any::get_type_id` remains unstable as *usage* of the `Any` trait will likely never require this, and the `Any` trait does not need to be implemented for any other types. As a result, this implementation detail can remain unstable until associated statics are implemented. * `Any::downcast_ref` is now stable * `Any::downcast_mut` is now stable * `BoxAny` remains unstable. While a direct impl on `Box<Any>` is allowed today it does not allow downcasting of trait objects like `Box<Any + Send>` (those returned from `Thread::join`). This is covered by #18737. * `BoxAny::downcast` is now stable. |
