module Nano_mutex: Nano_mutex
type
val invariant : t -> unit
val create : unit -> t
create () returns a new, unlocked mutex.
val equal : t -> t -> bool
equal is phys_equal
val current_thread_has_lock : t -> bool
current_thread_has_lock t returns true iff the current thread has t locked.
val lock : t -> unit Or_error.t
lock t locks the mutex t, blocking until it can be locked. lock immediately
returns Error if the current thread already holds t.
val lock_exn : t -> unit
val try_lock : t -> [ `Acquired | `Not_acquired ] Or_error.t
try_lock t locks t if it can immediately do so. The result indicates whether
try_lock succeeded in acquiring the lock. try_lock returns Error if the current
thread already holds t.
val try_lock_exn : t -> [ `Acquired | `Not_acquired ]
val unlock : t -> unit Or_error.t
unlock t unlocks t, if the current thread holds it. unlock returns Error if
the lock is not held by the calling thread.
val unlock_exn : t -> unit
val critical_section : t -> f:(unit -> 'a) -> 'a
val sexp_of_t : t -> Sexplib.Sexp.t
