A Moption is a mutable option, like 'a option ref, but with a more efficient implementation; in particular, set_some does not allocate.

type 'a t
include sig ... end
val sexp_of_t : ('a -> Ppx_sexp_conv_lib.Sexp.t) -> 'a t -> Ppx_sexp_conv_lib.Sexp.t
include Base.Invariant.S1 with type 'a t := 'a t
val invariant : ('a -> unit) -> 'a t -> unit
module Optional_syntax : sig ... end
val create : Base.Unit.t -> _ t
val is_none : _ t -> Base.Bool.t
val is_some : _ t -> Base.Bool.t
val get : 'a t -> 'a Base.Option.t
val get_some_exn : 'a t -> 'a
val unsafe_get : 'a t -> 'a

Does not check that is_some before unsafely accessing the stored value

val set : 'a t -> 'a Base.Option.t -> Base.Unit.t
val set_none : _ t -> Base.Unit.t
val set_some : 'a t -> 'a -> Base.Unit.t
