Struct DeviceProxy 

pub struct DeviceProxy { /* private fields */ }

Implementations

impl DeviceProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.usb.peripheral/Device.

pub fn take_event_stream(&self) -> DeviceEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn get_configuration( &self, ) -> QueryResponseFut<DeviceGetConfigurationResult, DefaultFuchsiaResourceDialect>

Retrieves the current device descriptor and active configuration descriptors.

Returns the active USB device descriptor and all associated configuration descriptors registered with the peripheral device manager.

• error:
  • ZX_ERR_BAD_STATE: The peripheral device has not been configured.

pub fn set_configuration( &self, device_desc: &DeviceDescriptor, config_descriptors: &[Vec<FunctionDescriptor>], ) -> QueryResponseFut<DeviceSetConfigurationResult, DefaultFuchsiaResourceDialect>

Sets the device’s descriptors, adds the functions and creates the child devices for the configuration’s interfaces. At least one function descriptor must be provided.

pub fn clear_functions( &self, ) -> QueryResponseFut<(), DefaultFuchsiaResourceDialect>

Tells the device to remove the child devices for the configuration’s interfaces and reset the list of functions to empty. The caller should wait for the FunctionsCleared event.

pub fn set_state_change_listener( &self, listener: ClientEnd<EventsMarker>, ) -> Result<(), Error>

Adds a state change listener that is invoked when a state change completes.

Returns true if the proxy has received the PEER_CLOSED signal.

fn on_closed(&self) -> OnSignals<'_, Unowned<'_, NullableHandle>>

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
