This PR reworks system so wrapping every device in
Device
is no longer needed.Device
is now a type ofRc<RefCell<dyn DynDevice>>
whereDynDevice
istrait DynDevice: Any + 'static + Transmutable
.That way the Transmutable methods can be called on the new Device type, making it work very similarly to the old one.
It also allows access to any device added to a system by calling
get_device
orget_device_by_name
on the system, with the type of the device as a generic. The generic is checked against the type id of thedyn DynDevice
and will error out if they don't match, a cast to a different device by accident is not possible. This system is used in the deno projects core for a resource table whic is used extensively.DynDevice
is implemented for every type that implementsTransmutable + 'static
, so devices do not have to implement it manually.Adding a new device to the system now returns a
DeviceId
which can be used to get access to the device again. If the id is unknown, devices can also be found through their set name (if they have one).The event queue and debuggables list now both hold device ids instead of the device directly.
There is now a
DeviceSettings
struct which can be used when adding a device to a system. Methods likeadd_addressable_device, add_interruptable_device, add_peripheral
still exists but useDeviceSettings
internaly
