[−][src]Struct usb_device::class::ControlIn

pub struct ControlIn<'a, 'p, 'o, B: UsbBus>(_);

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

Methods

impl<'a, 'p, 'o, B: UsbBus> ControlIn<'a, 'p, 'o, B>
[src]

pub fn request(&self) -> &Request
[src]

Gets the request from the SETUP packet.

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

Accepts the transfer with the supplied buffer.

pub fn accept(
    self,
    f: impl FnOnce(&mut [u8]) -> Result<usize>
) -> Result<()>
[src]

Accepts the transfer with a callback that can write to the internal buffer of the control pipe. Can be used to avoid an extra copy.

pub fn reject(self) -> Result<()>
[src]

Rejects the transfer by stalling the pipe.
