Struct ConfigurationProxy 

pub struct ConfigurationProxy { /* private fields */ }

Implementations

impl ConfigurationProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.usb.policy/Configuration.

pub fn take_event_stream(&self) -> ConfigurationEventStream

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<ConfigurationGetConfigurationResult, DefaultFuchsiaResourceDialect>

Retrieves the current USB device descriptor and active configuration descriptors.

Errors

• ZX_ERR_NOT_SUPPORTED: Peripheral function querying is not supported on the target hardware.

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

Sets and activates a new USB peripheral function configuration.

Teardown of the previous peripheral function stack occurs before initializing and binding the newly specified functions. The call completes once the peripheral controller and underlying function drivers are registered and ready.

Errors

• ZX_ERR_INVALID_ARGS: Configuration parameters are invalid.
• ZX_ERR_ALREADY_BOUND: An existing peripheral configuration is locked or undergoing transition.
• ZX_ERR_NOT_SUPPORTED: The requested combination of functions cannot be supported simultaneously.
