Implementations

impl UsbControlTransferResponder

pub fn send(self, result: Result<&[u8], i32>) -> Result<(), Error>

Sends a response to the FIDL transaction.

Trait Implementations

impl Debug for UsbControlTransferResponder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for UsbControlTransferResponder

Set the the channel to be shutdown (see UsbControlHandle::shutdown) if the responder is dropped without sending a response, so that the client doesn’t hang. To prevent this behavior, call drop_without_shutdown.

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Responder for UsbControlTransferResponder

type ControlHandle = UsbControlHandle

The control handle for this protocol.

fn control_handle(&self) -> &UsbControlHandle

Returns the ControlHandle for this protocol.

fn drop_without_shutdown(self)

Drops the responder without setting the channel to shutdown.
