Provided Methods

unsafe fn sensorReader_fetchingRequest_didFetchResult( &self, reader: &SRSensorReader, fetch_request: &SRFetchRequest, result: &SRFetchResult, ) -> bool

where Self: Sized + Message,

Invoked when a sample has been fetched

This callback can be called multiple times when there are multiple results.

Parameter fetchRequest: The request corresponding to the this result

Parameter result: One result of the fetch. The caller is expected to know what type of sample is returned.

Note: The fetchResult is not valid after the callback is complete. If the caller needs to access the result at a later time, it must be copied not merely retained

Returns: The delegate should return YES if the fetch should continue, NO if the fetch should stop

Safety

result generic should be of the correct type.

unsafe fn sensorReader_didCompleteFetch( &self, reader: &SRSensorReader, fetch_request: &SRFetchRequest, )

where Self: Sized + Message,

Invoked when a fetch has been completed successfully

unsafe fn sensorReader_fetchingRequest_failedWithError( &self, reader: &SRSensorReader, fetch_request: &SRFetchRequest, error: &NSError, )

where Self: Sized + Message,

Invoked when a fetch has completed with an error

unsafe fn sensorReader_didChangeAuthorizationStatus( &self, reader: &SRSensorReader, authorization_status: SRAuthorizationStatus, )

where Self: Sized + Message,

Invoked when authorization status has changed

unsafe fn sensorReaderWillStartRecording(&self, reader: &SRSensorReader)

where Self: Sized + Message,

Invoked after a SRSensorReader has request that recording be started for a sensor

unsafe fn sensorReader_startRecordingFailedWithError( &self, reader: &SRSensorReader, error: &NSError, )

where Self: Sized + Message,

Invoked if there was an error starting recording for a given sensor

unsafe fn sensorReaderDidStopRecording(&self, reader: &SRSensorReader)

where Self: Sized + Message,

Invoked after a SRSensorReader has request that recording be stopped for a sensor

unsafe fn sensorReader_stopRecordingFailedWithError( &self, reader: &SRSensorReader, error: &NSError, )

where Self: Sized + Message,

Invoked if there was an error starting recording for a given sensor

unsafe fn sensorReader_didFetchDevices( &self, reader: &SRSensorReader, devices: &NSArray<SRDevice>, )

where Self: Sized + Message,

unsafe fn sensorReader_fetchDevicesDidFailWithError( &self, reader: &SRSensorReader, error: &NSError, )

where Self: Sized + Message,
