Struct usbd_ccid::Ccid

pub struct Ccid<'bus, Bus, I, const N: usize>where
    Bus: 'static + UsbBus,
    I: 'static + Interchange<REQUEST = Vec<u8, N>, RESPONSE = Vec<u8, N>>,{ /* private fields */ }

Implementations

impl<'bus, Bus, I, const N: usize> Ccid<'bus, Bus, I, N>where
Bus: 'static + UsbBus,
I: 'static + Interchange<REQUEST = Vec<u8, N>, RESPONSE = Vec<u8, N>>,

pub fn new(
allocator: &'bus UsbBusAllocator<Bus>,
request_pipe: Requester<I>,
card_issuers_data: Option<&[u8]>
) -> Self

Class constructor.

The optional card issuer’s data may be of length at most 13 bytes, and allows personalizing the Answer-to-Reset, for instance by ASCII-encoding vendor or model information.

pub fn check_for_app_response(&mut self)

Read response from application (if any) and start writing it to the USB bus. Should be called before managing Bus.

pub fn did_start_processing(&mut self) -> Status

pub fn send_wait_extension(&mut self) -> Status

Trait Implementations

impl<'bus, Bus, I, const N: usize> UsbClass<Bus> for Ccid<'bus, Bus, I, N>where
Bus: 'static + UsbBus,
I: 'static + Interchange<REQUEST = Vec<u8, N>, RESPONSE = Vec<u8, N>>,

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

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

Gets a class-specific string descriptor.

fn poll(&mut self)

Called whenever the UsbDevice is polled.

fn endpoint_in_complete(&mut self, addr: EndpointAddress)

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

fn endpoint_out(&mut self, addr: EndpointAddress)

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

fn control_in(&mut self, transfer: ControlIn<'_, '_, '_, Bus>)

Called when a control request is received with direction DeviceToHost.

fn control_out(&mut self, transfer: ControlOut<'_, '_, '_, Bus>)

Called when a control request is received with direction HostToDevice.

fn get_bos_descriptors(
&self,
writer: &mut BosWriter<'_, '_>
) -> Result<(), UsbError>

Called when a GET_DESCRIPTOR request is received for a BOS descriptor. When called, the implementation should write its blobs such as capability descriptors into writer. The BOS descriptor itself will be written by UsbDevice and shouldn’t be written by classes.

fn reset(&mut self)

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

fn endpoint_setup(&mut 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.
