) -> ReturnCode
Perform an asynchronous read/write operation, whose completion is signaled by invoking SpiMasterClient.read_write_done on the provided client. write_buffer must be Some, read_buffer may be None. If read_buffer is Some, the length of the operation is the minimum of the size of the two buffers. Read more
