A server handler for the Device protocol.

Required Methods

fn get_info( &mut self, responder: Responder<GetInfo, ___T>, ) -> impl Future<Output = ()> + Send

fn config( &mut self, request: Request<Config, ___T>, responder: Responder<Config, ___T>, ) -> impl Future<Output = ()> + Send

Configures the given serial port. Values of flags are defined in the constants above.

• error one of the following values:

• `ZX_ERR_IO_NOT_PRESENT`: The serial controller is in a low-power state or is

•                          transitioning to a low-power state.

• Other values may be returned for driver- or device-specific errors.

fn enable( &mut self, request: Request<Enable, ___T>, responder: Responder<Enable, ___T>, ) -> impl Future<Output = ()> + Send

Enable or disable the device. If already enabled and enable is true, this is a no-op and returns successfully. If already disabled and enable is false, this is a no-op and returns successfully.

• request enable true to enable the device, or false to disable it.

• error one of the following values:

• `ZX_ERR_BAD_STATE`: `enable` was false, and a `Read()` or `Write()` call was pending.

• `ZX_ERR_IO_NOT_PRESENT`: The serial controller is in a low-power state or is

•                          transitioning to a low-power state.

fn read( &mut self, responder: Responder<Read, ___T>, ) -> impl Future<Output = ()> + Send

Perform a read operation. Returns immediately if data has been received since the last call; otherwise the request is completed the next time data is received (clients can use the hanging-get pattern to be notified of new data).

• response data the bytes read from the device.

• error one of the following values:

• `ZX_ERR_BAD_STATE`: The device was not enabled.

• `ZX_ERR_CANCELED`: The call was canceled by `CancelAll()`.

• `ZX_ERR_ALREADY_BOUND`: Another `Read()` call was already pending.

• `ZX_ERR_IO_NOT_PRESENT`: The serial controller is in a low-power state or is

•                          transitioning to a low-power state.

• Other values may be returned for driver- or device-specific errors.

fn write( &mut self, request: Request<Write, ___T>, responder: Responder<Write, ___T>, ) -> impl Future<Output = ()> + Send

Perform a write operation. Returns when all bytes have been written, or when an error is encountered.

• request data the bytes to write to the device.

• error one of the following values:

• `ZX_ERR_BAD_STATE`: The device was not enabled.

• `ZX_ERR_CANCELED`: The call was canceled by `CancelAll()`.

• `ZX_ERR_ALREADY_BOUND`: Another `Write()` call was already pending.

• `ZX_ERR_IO_NOT_PRESENT`: The serial controller is in a low-power state or is

•                          transitioning to a low-power state.

• Other values may be returned for driver- or device-specific errors.

fn cancel_all( &mut self, responder: Responder<CancelAll, ___T>, ) -> impl Future<Output = ()> + Send

Immediately cancels all outstanding asynchronous I/O

Provided Methods

fn on_unknown_interaction( &mut self, ordinal: u64, ) -> impl Future<Output = ()> + Send

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
