module CCBitField: sig .. end

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;;
   let x = B.mk_field ()
   let y = B.mk_field ()
   let z = B.mk_field ()
   let f = B.empty |> B.set x true |> B.set y true;;
   assert (not (B.get z f)) ;;
   assert (f |> B.set z true |> B.get z);;
  

exception TooManyFields

Raised when too many fields are packed into one bitfield

exception Frozen

Raised when a frozen bitfield is modified

val max_width : int

System-dependent maximum width for a bitfield, typically 30 or 62

module type S = sig .. end
