val create : bit:int -> Flags_intf.Int63.t
create ~bit:n
creates a flag with the n
th 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:
Flags.Make
builds a new flags module.
