pub const _spinTLStreamBufferHandlingModeEnums_StreamBufferHandlingMode_OldestFirstOverwrite: _spinTLStreamBufferHandlingModeEnums = 1;Expand description
< The application always gets the buffer from the head of the output buffer queue (thus, the oldest available one). If the output buffer queue is empty, the application waits for a newly acquired buffer until the timeout expires. If a new buffer arrives it will overwrite the existing buffer from the head of the queue (behaves like a circular buffer).
