Usage

Here's a basic example demonstrating how to use the event manager:

package main

import (
	"fmt"
	"github.com/NIR3X/eventmanager"
)

func main() {
	// Create a new EventManager instance.
	em := eventmanager.NewEventManager()

	// Add an event handler for "example_event".
	handlerId := em.AddHandler("example_event", func(data interface{}) {
		fmt.Printf("Received event: example_event, Data: %v\n", data)
	})

	// Trigger the "example_event" event.
	em.TriggerEvent("example_event", "Hello, world!")

	// Remove the event handler using the handler Id.
	em.RemoveHandler("example_event", handlerId)

	// Trigger the event again to verify removal.
	em.TriggerEvent("example_event", "Hello again!")
}
