Hello,
im tring to add nothrow keyword in my code, but compilation
fails :
function 'object.opEquals' is not nothrow
its a simple comparison between 2 objects. How to make
opEquals nothrow ?
You can't. Object.opEquals is not nothrow, so object.opEquals
is not nothrow (note the former is the virtual member
function, the latter is a global function which is what the
compiler actually calls).
It is a legacy limitation. Until we get rid of all the Object
base methods for things like opEquals and toHash, we will not
be able to fix this.

Im using DerelictGLFW3, to process events im doing this :
glfwSetMouseButtonCallback(window, &onMouseClick);
onMouseClick function must be nothrow.
But now I can't do anything in this function because I can't
convert my code to nothrow.
Can I put a try catch in the body ?
extern(C) nothrow
{
void onMouseClick(GLFWwindow* window, int button, int
action, int d)
{
try
{
// my code
}
catch
{
}
}
}
it seems its working but what about performances ?
thanks
You could also try assumeWontThrow.
