Required Methods§
Sourcefn start(
&mut self,
sender: &ServerSender<___T, Driver>,
request: RequestBuffer<___T, Start>,
responder: Responder<Start>,
)
fn start( &mut self, sender: &ServerSender<___T, Driver>, request: RequestBuffer<___T, Start>, responder: Responder<Start>, )
Starts the driver with the given |start_args|.
Drivers should finish their initial setup and enumeration before returning from |Start|.
In particular they should enumerate all currently available nodes by utilizing
fuchsia.driver.framework/Node.AddChild
and waiting for all calls to be completed.
The Framework will not consider the driver to be started until this call has returned successfully. Therefore a driver will not have |Stop| called on it until after it has replied to |Start| successfully.
If a driver returns an error, it will not have |Stop| called on it before the Driver Framework initiates shutdown of the driver’s dispatchers. Therefore it should have performed all necessary cleanup before returning an error.
Sourcefn stop(&mut self, sender: &ServerSender<___T, Driver>)
fn stop(&mut self, sender: &ServerSender<___T, Driver>)
Stops the driver. To stop, the driver should teardown any resources it set up in or after |Start|. This is a one-way FIDL method. When the driver has completed stopping, it should close its server end. Asynchronous operations should fully complete before closing the server end.
