Struct MemorySink 

pub struct MemorySink { /* private fields */ }

In-memory sink that stores only the last finalized run.

MemorySink writes no file artifact and keeps the most recent finalized Run in memory. Later writes replace earlier stored runs.

Storing finalized runs clones captured data and can increase memory use for large captures.

Returns a cloned copy of the last finalized run, if present.
