Walkthrough

The update modifies the process_stream function in src/server.rs by removing an internal Tokio task spawn. Instead of spawning a new asynchronous task to handle each connection, the code now directly awaits the connection handler, accompanied by a clarifying comment about the change.

Changes

File(s) Change Summary
src/server.rs Removed redundant tokio::spawn in process_stream; added explanatory comment.

Poem

A rabbit hopped through server code,
Where nested tasks once overflowed.
With one less spawn, the stream runs neat,
Awaiting calmly, light on its feet.
Now connections flow, no extra thread,
The burrow’s faster—enough said! 🐇

396-400: Eliminating the extra tokio::spawn is the right call

Running handle_connection directly inside the already-spawned process_stream task removes an unnecessary layer of scheduling overhead and ensures the connection future is tied to the worker’s cancellation scope. Nice catch.
