Module type Flags

Signature

module type Make_arg = Make_arg
module type S = S
val create : bit:int -> Int63.t

create ~bit:n creates a flag with the nth bit set. n must be between 0 and 62.

Typically a flag has one bit set; create is useful in exactly those cases. For flags with multiple bits one can either define the Int63.t directly or create it in terms of simpler flags, using + and -.

module Make (M : Make_arg) : S with type t = Int63.t
Flags.Make builds a new flags module.
