Module Picos_std_sync.MutexSource
A mutual-exclusion lock or mutex.
ℹ️ This intentionally mimics the interface of Stdlib.Mutex. Unlike with the standard library mutex, blocking on this mutex potentially allows an effects based scheduler to run other fibers on the thread.
🏎️ The optional checked argument taken by most of the operations defaults to true. When explicitly specified as ~checked:false the mutex implementation may avoid having to obtain the current fiber, which can be expensive relative to locking or unlocking an uncontested mutex. Note that specifying ~checked:false on an operation may prevent error checking also on a subsequent operation.
Represents a mutual-exclusion lock or mutex.
create () returns a new mutex that is initially unlocked.
lock mutex locks the mutex.
ℹ️ If the fiber has been canceled and propagation of cancelation is allowed, this may raise the cancelation exception before locking the mutex. If ~checked:false was specified, the cancelation exception may or may not be raised.
try_lock mutex locks the mutex in case the mutex is unlocked. Returns true on success and false in case the mutex was locked.
ℹ️ If the fiber has been canceled and propagation of cancelation is allowed, this may raise the cancelation exception before locking the mutex. If ~checked:false was specified, the cancelation exception may or may not be raised.
unlock mutex unlocks the mutex.
ℹ️ This operation is not cancelable.
protect mutex thunk locks the mutex, runs thunk (), and unlocks the mutex after thunk () returns or raises.
ℹ️ If the fiber has been canceled and propagation of cancelation is allowed, this may raise the cancelation exception before locking the mutex. If ~checked:false was specified, the cancelation exception may or may not be raised.
