Provided Methods

unsafe fn readerSessionDidBecomeActive(&self, session: &NFCVASReaderSession)

where Self: Sized + Message,

Parameter session: The session object in the active state.

Gets called when the NFC reader session has become active. RF is enabled and reader is scanning for VAS tags. The

 readerSession:didReceiveVASResponses: @link/ will be called when a VAS transaction is completed.
  

unsafe fn readerSession_didInvalidateWithError( &self, session: &NFCVASReaderSession, error: &NSError, )

where Self: Sized + Message,

Parameter session: The session object that is invalidated.

Parameter error: The error indicates the invalidation reason.

Gets called when a session becomes invalid. At this point the client is expected to discard the returned session object.

unsafe fn readerSession_didReceiveVASResponses( &self, session: &NFCVASReaderSession, responses: &NSArray<NFCVASResponse>, )

where Self: Sized + Message,

Parameter session: The session object used for tag detection.

Parameter responses: Array of

 NFCVASResponse @link/ objects.  The order of the response objects follows the
                  sequence of GET VAS DATA sent by the reader session.

 @discussion      Gets called when the reader completes the requested VAS transaction.  Polling
                  is automatically restarted once the detected tag is removed from the reader's read range.

Dyn Compatibility

This trait is dyn compatible.

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