Struct usb_device::test_class::TestClass

pub struct TestClass<'a, B: UsbBus> { /* private fields */ }

Test USB class for testing USB driver implementations. Supports various endpoint types and requests for testing USB peripheral drivers on actual hardware.

Implementations

impl<B: UsbBus> TestClass<'_, B>

pub fn new(alloc: &UsbBusAllocator<B>) -> TestClass<'_, B>

Creates a new TestClass.

pub fn make_device<'a>(
    &'a self,
    usb_bus: &'a UsbBusAllocator<B>
) -> UsbDevice<'a, B>

Convenience method to create a UsbDevice that is configured correctly for TestClass.

pub fn poll(&self)

Must be called after polling the UsbDevice.

Trait Implementations

impl<B: UsbBus> UsbClass<B> for TestClass<'_, B>

fn reset(&self)

Called after a USB reset after the bus reset sequence is complete.

fn get_configuration_descriptors(
    &self,
    writer: &mut DescriptorWriter<'_>
) -> Result<()>

Called when a GET_DESCRIPTOR request is received for a configuration descriptor. When called, the implementation should write its interface, endpoint and any extra class descriptors into writer. The configuration descriptor itself will be written by UsbDevice and shouldn’t be written by classes.

fn endpoint_in_complete(&self, addr: EndpointAddress)

Called when endpoint with address addr has completed transmitting data (IN packet).

fn endpoint_out(&self, addr: EndpointAddress)

Called when endpoint with address addr has received data (OUT packet).

fn control_in(&self, xfer: ControlIn<'_, '_, '_, B>)

Called when a control request is received with direction DeviceToHost.

fn control_out(&self, xfer: ControlOut<'_, '_, '_, B>)

Called when a control request is received with direction HostToDevice.

fn get_string(&self, index: StringIndex, lang_id: u16) -> Option<&str>

Gets a class-specific string descriptor.

fn endpoint_setup(&self, addr: EndpointAddress)

Called when endpoint with address addr has received a SETUP packet. Implementing this shouldn’t be necessary in most cases, but is provided for completeness’ sake.
