A very simple, 0-overhead, and yet type-safe 1-file library for doing bitwise operations between masks represented by enums.

For example, given: ``` enum ClearBufferMask { GL_DEPTH_BUFFER_BIT = 0x00000100, GL_ACCUM_BUFFER_BIT = 0x00000200, GL_STENCIL_BUFFER_BIT = 0x00000400, GL_COLOR_BUFFER_BIT = 0x00004000, };

void glClear(unsigned int mask); ```

the problem is that any bitwise operation between ClearBufferMask elements will loose the type, and will be casted to int. Thus, type-checking will be disabled, and glClear() can be called with any integer value.

bitwise_enum class wrapper just provides all the bitwise operations over a given enum (as a template parameter), always keeping the type. Given that, glClear can now be declared as: ``` void glClear( bitwise_enum mask );`

int main() { glClear( GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT ); // OK glClear( 0x00004000 | 0x00000100); // ERROR! } ```

Just include bitwise_enums.hpp and you are ready to use it.
