feat: add permit APIs and notification_capacity to HandlerCtx#40
Conversation
Expose backpressure-aware permit APIs on HandlerCtx that mirror tokio's mpsc::Sender reserve surface. Users can now reserve channel capacity before sending, with both borrowed and owned permit types. New types: NotifyPermit, OwnedNotifyPermit New methods: permit, permit_owned, try_permit, try_permit_owned, permit_many, try_permit_many, notification_capacity Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
