The current situation, where the reader owns the namespace buffer leads to an inconvenient api.
In the inner loop of the
read_namespaced_event, the reader, mutably borrowed cannot be used, notably for decoding the event. The workaround, having temporary variables is not satisfactory (more boilerplate and additional checks).Making the caller own the buffer fixes the situation, while still avoiding extra allocation.
