Struct DataPointStore 

pub struct DataPointStore { /* private fields */ }

Shared in-memory store for named data points.

Written by DatapointBackend::dispatch (keyed by the dot-joined namespace of the trace object) and read by the forwarder’s DataPoint mini-protocol handler when the acceptor queries a named data point.

DataPointStore is cheap to clone — all clones share the same underlying HashMap.
