Struct Hub
pub struct Hub { /* private fields */ }Available on crate feature
unstable-wgpu-24 only.Expand description
All the resources tracked by a crate::global::Global.
§Locking
Each field in Hub is a [Registry] holding all the values of a
particular type of resource, all protected by a single RwLock.
So for example, to access any Buffer, you must acquire a read
lock on the Hubs entire buffers registry. The lock guard
gives you access to the Registry’s Storage, which you can
then index with the buffer’s id. (Yes, this design causes
contention; see [#2272].)
But most wgpu operations require access to several different
kinds of resource, so you often need to hold locks on several
different fields of your Hub simultaneously.
Inside the Registry there are Arc<T> where T is a Resource
Lock of Registry happens only when accessing to get the specific resource
