objc2
is a replacement forobjc
that contains a bunch of safety and performance improvements, includingId
andmsg_send_id!
which automatically upholds memory management rules.Specifically for glfw-rs, this is likely ever so slightly faster, as the message sending can be done without needing to put the view into an autorelease pool.Perhaps not, since we now also check the returned value.Note: We could've used
objc2-app-kit
to avoid the manualmsg_send_id!
here, but the extra dependency seemed excessive.
