Toplevel functions

The functions below are broadly useful when writing Async programs, and so are made available at the toplevel.

val choose : 'a Deferred.Choice.t list -> 'a Deferred.t
val don't_wait_for : unit Deferred.t -> unit
val every : ?⁠start:unit Async_kernel__.Clock_intf.Deferred.t -> ?⁠stop:unit Async_kernel__.Clock_intf.Deferred.t -> ?⁠continue_on_error:bool -> Async_kernel__.Import.Time_ns.Span.t -> (unit -> unit) -> unit

Infix operators and Let_syntax support

include Core_kernel.Monad.Infix with type 'a t := 'a Deferred.t
type 'a t
val (>>=) : 'a t -> ('a -> 'b t) -> 'b t

t >>= f returns a computation that sequences the computations represented by two monad elements. The resulting computation first does t to yield a value v, and then runs the computation returned by f v.

val (>>|) : 'a t -> ('a -> 'b) -> 'b t

t >>| f is t >>= (fun a -> return (f a)).

val (>>>) : 'a Async_kernel__Deferred.t -> ('a -> unit) -> unit

equivalent to Deferred.upon.

val (>>=?) : ('a, 'b) Deferred.Result.t -> ('a -> ('c, 'b) Deferred.Result.t) -> ('c, 'b) Deferred.Result.t

equivalent to Deferred.Result.bind.

val (>>|?) : ('a, 'b) Deferred.Result.t -> ('a -> 'c) -> ('c, 'b) Deferred.Result.t

equivalent to Deferred.Result.map.

include Deferred.Let_syntax
val return : 'a -> 'a Deferred.t
include Base__.Monad_intf.Infix with type 'a t := 'a Deferred.t
type 'a t
val (>>=) : 'a t -> ('a -> 'b t) -> 'b t

t >>= f returns a computation that sequences the computations represented by two monad elements. The resulting computation first does t to yield a value v, and then runs the computation returned by f v.

val (>>|) : 'a t -> ('a -> 'b) -> 'b t

t >>| f is t >>= (fun a -> return (f a)).
