source 
pub struct DeviceController { /* private fields */ }
Expand description

A single manager for both a device and an associated DeviceEventStream.

Implementations§

source§

impl DeviceController

source

pub fn events(&self) -> &DeviceEventStream

Get a reference to the event stream.

source

pub fn device(&self) -> &Device

Get a reference to the device.

source

pub fn new_from_device(device: Device) -> Self
