safe enum
for anyone who doesn't know, this "-Werror=switch-enum" compiler option make the compiler throw an error if all of the enum values aren't explicitly handled in a "switch" statement
enum class colors {
blue,
red,
purple,
}
void func(colors c)
{
switch(c)
{
case colors::blue:
// do something
break;
case colors::red:
// do something
break;
default:
// do something
break;
}
}
int main()
{
func(colors::blue);
}
this code doesn't compile on clang and gcc with the option "-Werror=switch-enum" because the "colors::purple" isn't explicitly handled. be aware that it doesn't throw a compiler error for "if" statements if one of the values isn't handled
