Expand description

A factory trait for creating devices.

Implement this trait to add support for new protocols or device types.

§Example

struct ModbusDeviceFactory;

impl DeviceFactory for ModbusDeviceFactory {
    fn protocol(&self) -> Protocol {
        Protocol::ModbusTcp
    }

    fn create(&self, config: DeviceConfig) -> Result<BoxedDevice> {
        Ok(Box::new(ModbusDevice::new(config)?))
    }
}
