pub struct Id<T: Marker>(/* private fields */);
Expand description
An identifier for a wgpu object.
An Id<T>
value identifies a value stored in a Global
’s Hub
.
§Note on Id
typing
You might assume that an Id<T>
can only be used to retrieve a resource of
type T
, but that is not quite the case. The id types in wgpu-core
’s
public API (TextureId
, for example) can refer to resources belonging to
any backend, but the corresponding resource types (Texture<A>
, for
example) are always parameterized by a specific backend A
.
So the T
in Id<T>
is usually a resource type like Texture<Empty>
,
where Empty
is the wgpu_hal
dummy back end. These empty types are
never actually used, beyond just making sure you access each Storage
with
the right kind of identifier. The members of Hub<A>
pair up each
X<Empty>
type with the resource type X<A>
, for some specific backend
A
.
