Monad.Seq
The Sequence monad.
The sequence monad is the same as the list monad, except the sequences are used to represent multiple results.

with type 'a t = 'a Core_kernel.Sequence.t
and type 'a m = 'a

include Monad with type 'a t := 'a t
sequence xs
computes a sequence of computations xs
in the left to right order.
module Fn : sig ... end
Various function combinators lifted into the Kleisli category.
module Pair : sig ... end
The pair interface lifted into the monad.
module Triple : sig ... end
The triple interface lifted into a monad.
module Lift : sig ... end
Lifts functions into the monad.
module Exn : sig ... end
Interacting between monads and language exceptions
module Collection : sig ... end
Lifts collection interface into the monad.
module List : Collection.S with type 'a t := 'a list
The Monad.Collection.S interface for lists
module Seq : Collection.S with type 'a t := 'a Core_kernel.Sequence.t
The Monad.Collection.S interface for sequences

val pure : 'a -> 'a t
pure x
creates a computation that results in x
.
val accept : 'a -> 'a t
accept x
accepts x
as a result of computation. (Same as pure x
.
val reject : unit -> 'a t
reject ()
rejects the rest of computation sequence, and terminate the computation with the zero
result (Same as zero ()
val guard : bool -> unit t
guard cond
ensures cond
is true
in the rest of computation. Otherwise the rest of the computation is rejected.
