Type definitions for putting shared ownership and synchronized mutation behind the threading
feature toggle.
That way, single-threaded applications will not have to use thread-safe primitives, and simply do not specify the ‘threading’ feature.
Functions
- Downgrade a handle previously obtained with
get_mut()
to drop mutation support. - Get a mutable reference through a
MutableOnDemand
for read-write access. - Get a shared reference through a
MutableOnDemand
for read-only access. - Get a mutable reference through a
Mutable
for read-write access. - Get a mutable reference to the underlying data, with semantics similar to Arc::make_mut().
- Map a read guard into a sub-type it contains.
Type Aliases
- A mapped reference created from a
RefGuard
- A synchronization primitive which provides read-write access right away.
- A synchronization primitive which can start read-only and transition to support mutation.
- OnceCell
once_cell
A thread-safe cell which can be written to only once. - A reference counted pointer type for shared ownership.
- A guarded reference suitable for safekeeping in a struct.
