Module `Moonpool_fib.Fls`Source

Fiber-local storage.

This storage is associated to the current fiber, just like thread-local storage is associated with the current thread.

See Moonpool.Task_local_storage for more general information, as this is based on it.

NOTE: it's important to note that, while each fiber has its own storage, spawning a sub-fiber f2 from a fiber f1 will only do a shallow copy of the storage. Values inside f1's storage will be physically shared with f2. It is thus recommended to store only persistent values in the local storage.

Sourcetype 'a t = 'a Picos.Fiber.FLS.t

Sourceval create : unit -> 'a t

create () makes a new key. Keys are expensive and should never be allocated dynamically or in a loop.

Sourceexception Not_set

Sourceval get_exn : 'a t -> 'a

get k gets the value for the current task for key k. Must be run from inside a task running on a runner.

raises Not_set
otherwise

Sourceval get_opt : 'a t -> 'a option

get_opt k gets the current task's value for key k, or None if not run from inside the task.

Sourceval get : 'a t -> default:'a -> 'a

Sourceval set : 'a t -> 'a -> unit

set k v sets the storage for k to v. Must be run from inside a task running on a runner.

raises Failure
otherwise

Sourceval with_value : 'a t -> 'a -> (unit -> 'b) -> 'b

with_value k v f sets k to v for the duration of the call to f(). When f() returns (or fails), k is restored to its old value.

Local `Hmap.t`

This requires hmap to be installed.
