Module git_features::threading

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_mut_to_refparallel

Downgrade a handle previously obtained with get_mut() to drop mutation support.

get_mutparallel

Get a mutable reference through a MutableOnDemand for read-write access.

get_refparallel

Get a shared reference through a MutableOnDemand for read-only access.

lockparallel

Get a mutable reference through a Mutable for read-write access.

map_refparallel

Map a read guard into a sub-type it contains.

Type Definitions

MappedRefGuardparallel

A mapped reference created from a RefGuard

Mutableparallel

A synchronization primitive which provides read-write access right away.

MutableOnDemandparallel

A synchronization primitive which can start read-only and transition to support mutation.

OnceCellparallel and once_cell

A thread-safe cell which can be written to only once.

OwnSharedparallel

A reference counted pointer type for shared ownership.

RefGuardparallel

A guarded reference suitable for safekeeping in a struct.
