Struct usb_device::class::ControlOut

source · [−]

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

Expand description

Handle for a control OUT transfer. When implementing a class, use the methods of this object to response to the transfer with an ACT or an error (STALL condition). To ignore the request and pass it on to the next class, simply don’t call any method.

Implementations

impl<'a, 'p, 'r, B: UsbBus> ControlOut<'a, 'p, 'r, B>

pub fn request(&self) -> &Request

Gets the request from the SETUP packet.

pub fn data(&self) -> &[u8]

Gets the data from the data stage of the request. May be empty if there was no data stage.

pub fn accept(self) -> Result<()>

Accepts the transfer by succesfully responding to the status stage.

pub fn reject(self) -> Result<()>

Rejects the transfer by stalling the pipe.
