Is there a class which, rather than copying data written to it into an internal array which is occasionally resized (as MemoryStream does), retains a reference to each buffer that users pass into it on write, and maintains a data structure which keeps track of each buffer written and the offset/count? It should also support a read mechanism which will provide clients with a buffer, offset, and count (rather than requiring clients to allocate and provide a buffer into which the data is copied for each read).
Essentially I need something which retains data by reference and doesn’t do any significant allocations or any data copying behind my back. For some reason I doubt the BCL provides this. Any known implementations?
Would a
do?
