1//! # Tauri Plugin Redb Cache
2//!
3//! A Tauri plugin for HTTP and image caching using Redb with LRU memory cache and compression.
4//!
5//! ## Features
6//! - Two-tier caching: LRU memory cache + Redb persistent storage
7//! - Automatic Zlib compression for large data (>1KB)
8//! - Separate tables for HTTP responses and images
9//! - Configurable TTL, memory cache size, and compression threshold
10//! - Background cleanup task for expired entries
11//!
12//! ## Usage
13//! ```rust
14//! fn main() {
15//!     tauri::Builder::default()
16//!         .plugin(tauri_plugin_redb_cache::Builder::new().build())
17//!         .run(tauri::generate_context!())
18//!         .unwrap();
19//! }
20//! ```
