Crate czdb 

CZDB Database Library

A Rust library for parsing and searching CZ-format IP geolocation databases.

Features

• Supports both IPv4 and IPv6 address searches.
• Disk-based search (CzdbDisk) for low memory usage.
• Optional memory-mapped file support (mmap feature) via CzdbMmap.
• In-memory accelerated search via CzdbMemory (available by default).

Usage

1. Create a database instance by loading the database file and providing a decryption key:

use czdb::CzdbDisk;

let db_path = "path/to/your/czdb_file";
let key = "your_base64_key";
let mut czdb = CzdbDisk::open(db_path, key).expect("Failed to load database");

2. Search for IP address geolocation data:

use std::net::IpAddr;

let ip: IpAddr = "8.8.8.8".parse().unwrap();
if let Some(location) = czdb.search(ip) {
    println!("Location for IP {}: {}", ip, location);
} else {
    println!("No location data found for IP {}", ip);
}

纯真CZDB解析库

这是一个用于解析和查询 CZDB 格式 IP 地理位置数据库的 Rust 库。

功能

• 支持 IPv4 和 IPv6 地址查询。
• 提供磁盘搜索（CzdbDisk）、可选 mmap（CzdbMmap）和可选内存加速（CzdbMemory）。

使用方法

1. 创建实例并加载数据库：

use czdb::CzdbDisk;

let db_path = "path/to/your/czdb_file";
let key = "your_base64_key";
let mut czdb = CzdbDisk::open(db_path, key).expect("Failed to load database");

2. 查询 IP 数据：

use std::net::IpAddr;
let ip: IpAddr = "8.8.8.8".parse().unwrap();
if let Some(location) = czdb.search(ip) {
    println!("Location for IP {}: {}", ip, location);
} else {
    println!("No location data found for IP {}", ip);
}
