Bit Field

This module defines efficient bitfields up to 30 or 62 bits (depending on the architecture) in a relatively type-safe way.

module B = CCBitField.Make(struct end);;

#install_printer B.pp;;

module X = (val B.int ~name:"x" ~width:3 ());;
module Y = (val B.int ~name:"y" ~width:2 ());;
module Z = (val B.bool ~name:"z" ());;

let f = B.empty |> X.set 3 |> Y.set 1;;

Z.get f ;;

f |> Z.set true |> Z.get ;;

Format.printf "f: %a@." B.pp f;;
