Type Alias EndpointIn

pub type EndpointIn<'a, B> = Endpoint<'a, B, In>;

A device-to-host (IN) endpoint.

Aliased Type

struct EndpointIn<'a, B> { /* private fields */ }

Implementations

impl<B: UsbBus, D: EndpointDirection> Endpoint<'_, B, D>

pub fn address(&self) -> EndpointAddress

Gets the endpoint address including direction bit.

pub fn ep_type(&self) -> EndpointType

Gets the endpoint transfer type.

pub fn max_packet_size(&self) -> u16

Gets the maximum packet size for the endpoint.

pub fn interval(&self) -> u8

Gets the poll interval for interrupt endpoints.

pub fn stall(&self)

Sets the STALL condition for the endpoint.

pub fn unstall(&self)

Clears the STALL condition of the endpoint.

impl<B: UsbBus> Endpoint<'_, B, In>

pub fn write(&self, data: &[u8]) -> Result<usize>

Writes a single packet of data to the specified endpoint and returns number of bytes actually written. The buffer must not be longer than the max_packet_size specified when allocating the endpoint.

Errors

Note: USB bus implementation errors are directly passed through, so be prepared to handle other errors as well.

• WouldBlock - The transmission buffer of the USB peripheral is full and the packet cannot be sent now. A peripheral may or may not support concurrent transmission of packets.
• BufferOverflow - The data is longer than the max_packet_size specified when allocating the endpoint. This is generally an error in the class implementation.
