pub struct DeviceSynchronousProxy { /* private fields */ }

Implementations

impl DeviceSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<DeviceEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn get_configuration( &self, ___deadline: MonotonicInstant, ) -> Result<DeviceGetConfigurationResult, Error>

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>], ___deadline: MonotonicInstant, ) -> Result<DeviceSetConfigurationResult, Error>

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, ___deadline: MonotonicInstant, ) -> Result<(), Error>

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.
