t is an appendable type for defining nonempty_getter accessors. See the documentation of Accessor.nonempty_getter for more information.
include Base.Monad.S with type 'a t := 'a tt >>= 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.
module Monad_infix : sig ... endval return : 'a -> 'a treturn v returns the (trivial) computation that returns v.
ignore_m t is map t ~f:(fun _ -> ()). ignore_m used to be called ignore, but we decided that was a bad name, because it shadowed the widely used Stdlib.ignore. Some monads still do let ignore = ignore_m for historical reasons.
Like all, but ensures that every monadic value in the list produces a unit value, all of which are discarded rather than being collected into a list.
module Let_syntax : sig ... endThese are convenient to have in scope when programming with a monad:
val access : 'a -> 'a taccess a "accesses" a.
append a b accesses everything a accesses, then accesses everything b accesses.
