Module Moonpool_fib.Fiber

Fibers.

A fiber is a lightweight computation that runs cooperatively alongside other fibers. In the context of moonpool, fibers have additional properties:

type 'a t

A fiber returning a value of type 'a.

val res : 'a t -> 'a Moonpool.Fut.t

Future result of the fiber.

type 'a callback = 'a Moonpool.Exn_bt.result -> unit

Callbacks that are called when a fiber is done.

type cancel_callback = Moonpool.Exn_bt.t -> unit
type any =
  1. | Any : _ t -> any

Type erased fiber

val self : unit -> any

self () is the current fiber. Must be run from inside a fiber.

  • raises Failure

    if not run from inside a fiber.

val peek : 'a t -> 'a Moonpool.Fut.or_error option

Peek inside the future result

val is_done : _ t -> bool

Has the fiber completed?

val is_cancelled : _ t -> bool

Has the fiber completed with a failure?

val is_success : _ t -> bool

Has the fiber completed with a value?

val await : 'a t -> 'a

await fib is like Fut.await (res fib)

val wait_block_exn : 'a t -> 'a

wait_block_exn fib is Fut.wait_block_exn (res fib). NOTE: See Fut.wait_block for warnings about deadlocks.

val wait_block : 'a t -> 'a Moonpool.Fut.or_error

wait_block fib is Fut.wait_block (res fib). NOTE: See Fut.wait_block for warnings about deadlocks.

val check_if_cancelled : unit -> unit

Check if the current fiber is cancelled, in which case this raises. Must be run from inside a fiber.

  • raises Failure

    if not.

val yield : unit -> unit

Yield control to the scheduler from the current fiber.

  • raises Failure

    if not run from inside a fiber.

val with_cancel_callback : _ t -> cancel_callback -> (unit -> 'a) -> 'a

with_cancel_callback fib cb (fun () -> <e>) evaluates e in a scope in which, if the fiber fib is cancelled, cb() is called. If e returns without the fiber being cancelled, this callback is removed.

val with_self_cancel_callback : cancel_callback -> (unit -> 'a) -> 'a

with_self_cancel_callback cb f calls f() in a scope where cb is added to the cancel callbacks of the current fiber

val on_result : 'a t -> 'a callback -> unit

Wait for fiber to be done and call the callback with the result. If the fiber is done already then the callback is invoked immediately with its result.

val spawn_top : on:Moonpool.Runner.t -> (unit -> 'a) -> 'a t

spawn_top ~on f spawns a new (toplevel) fiber onto the given runner. This fiber is not the child of any other fiber: its lifetime is only determined by the lifetime of f().

spawn_link ~protect f spawns a sub-fiber f_child from a running fiber parent. The sub-fiber f_child is attached to the current fiber and fails if the current fiber parent fails.

  • parameter protect

    if true, when f_child fails, it does not affect parent. If false, f_child failing also causes parent to fail (and therefore all other children of parent).

    Must be run from inside a fiber.

  • raises Failure

    if not run from inside a fiber.

type cancel_handle

An opaque handle for a single cancel callback in a fiber

val add_on_cancel : _ t -> cancel_callback -> cancel_handle

add_on_cancel fib cb adds cb to the list of cancel callbacks for fib. If fib is already cancelled, cb is called immediately.

remove_on_cancel fib h removes the cancel callback associated with handle h.

Fiber-local storage.

Underlying storage for a task

A key used to access a particular (typed) storage slot on every task.

val new_key : init:(unit -> 'a) -> unit -> 'a key

new_key ~init () makes a new key. Keys are expensive and should never be allocated dynamically or in a loop. The correct pattern is, at toplevel:

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.
