//! RustFS Notify - A flexible and extensible event notification system for object storage.
//!
//! This library provides a Rust implementation of a storage bucket notification system.
//! It supports sending events to various targets
//! (like Webhook and MQTT) and includes features like event persistence and retry on failure.
