Module Moonpool_private.Ws_deque_

Work-stealing deque.

Adapted from "Dynamic circular work stealing deque", Chase & Lev.

However note that this one is not dynamic in the sense that there is no resizing. Instead we return false when push fails, which keeps the implementation fairly lightweight.

type 'a t

Deque containing values of type 'a

val create : dummy:'a -> unit -> 'a t

Create a new deque.

val push : 'a t -> 'a -> bool

Push value at the bottom of deque. returns true if it succeeds. This must be called only by the owner thread.

val pop : 'a t -> 'a option

Pop value from the bottom of deque. This must be called only by the owner thread.

val steal : 'a t -> 'a option

Try to steal from the top of deque. This is thread-safe.

val size : _ t -> int
