Stub module contains types for stubs for non-std environments and for std environments.

RwLock

A reader-writer lock which is exclusively locked for writing or shared for reading. This reader-writer lock will block threads waiting for the lock to become available. The lock can also be statically initialized or created via a RwLock::new RwLock wrapper to make spin::RwLock API compatible with std::sync::RwLock to swap

RwLockReadGuard

RAII structure used to release the shared read access of a lock when dropped.

RwLockWriteGuard

RAII structure used to release the exclusive write access of a lock when dropped.

SyncOnceCell

ThreadId
