= FFI::Bitmask < FFI::Enum

(from /home/chedong/.local/share/rdoc)
------------------------------------------------------------------------
Represents a C enum whose values are power of 2

@example
  enum {
    red = (1<<0),
    green = (1<<1),
    blue = (1<<2)
  }

Contrary to classical enums, bitmask values are usually combined when
used.
