Passing a pooled array to HashSet/StreamAdd and similar methods.

I have a usecase where allocations need to be minimized and there are scenarios where I get a T[] as an input that needs to be converted to either NameValueEntry[] or HashEntry[] before I can invoke StreamAdd() or HashSet().

One way to tackle this would be to create a buffer using the ArrayPool e.g.

T[] incoming = ...
NameValueEntry[] buffer = ArrayPool<NameValueEntry>.Shared.Rent(incoming.Length)
// copy the items from incoming to buffer
db.StreamAdd(key, buffer);

However given that the buffer.Length returned by the pool is not necessarily same as the requested incoming.Length there is no way for me to indicate how many items StreamAdd()/HashSet() should take.

Would it be possible to create an overload which could support this?

Start by locating the StreamAdd, HashSet, and similar overloads in the StackExchange.Redis client API and review how array lengths are currently handled. Determine the API shape needed to pass the number of valid elements in an ArrayPool-rented buffer, then verify that the overloads use only that range and preserve existing behavior.
