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