a lambda template used to generate the pipeline that will be set up as a push chain.
true (default) if you wish to auto-flush the push pipeline when all references to it are gone. This moves the whole chain into a RefCounted struct which automatically flushes any remaining data that hasn't been flushed.
An ioPipe to be used as the source for the data being pushed.
A wrapped chain that will push any data that is released as needed (i.e. as the buffer fills up).
Note: If autoFlush is false, you will need to manually call flush on the pipeline after all processing is done.
Convenience mechanism to wrap a specified output pipeline with a holding loop. It avoids having to explicitly specify the loop begin and end.
