fix(discord): spawn handle_message to unblock event loop#430
Merged
Conversation
Wraps the handle_message() call in tokio::spawn so the serenity event handler returns immediately. This prevents a long-running streaming response from blocking all other incoming Discord messages. Fixes #429

Problem
When one session is streaming a long response, all other incoming Discord messages are blocked until the streaming completes. The serenity event handler awaits
handle_message()directly, which runs the entire streaming loop (30s+) before returning. This serializes all concurrent sessions behind one active response.Reported in #429.
Fix
Wrap the
handle_message()call intokio::spawnso the event handler returns immediately. The router isArc<AdapterRouter>, so cloning is cheap. All other variables (adapter,thread_channel,sender,prompt,extra_blocks,trigger_msg) are moved into the spawned task.Changes
src/discord.rs: Cloneself.router(Arc) and spawnhandle_messageas a detached tokio task instead of awaiting it inline.Fixes #429
