EventBus is a lightweight, type-safe event dispatching library for Go. It allows registering listeners for specific event types and dispatching events in a structured, concurrency-safe way.

• Type-matching listeners using reflect.Type
• Supports multi-parameter listener functions
• Safe event dispatching via locking
• Optional debug logging using slog
• Lightweight and dependency-free

go get github.com/yourusername/event

Creates a new event bus with the given name.

Sets an optional logger for debug output.

Unlocks the bus, preventing further listener registration and allowing event dispatching.

Registers a listener function. Panics if registration fails.

Safe variant of Listen that returns an error instead of panicking.

Dispatches an event. Only listeners matching the event type will be invoked.

• Listeners can be multi-parameter functions; they will be triggered only when all required event types have been received.
• The event bus must be unlocked before sending events. Listener registration is disabled afterward to ensure consistency.
