/*! 🔌 SocketBox - TCP/UDP Socket networking
|
||
*
|
||
* ## 📝 概要
|
||
* Rustの std::net を基盤とした高性能ネットワーキング Box
|
||
* TCP サーバー・クライアント両対応、HTTPサーバー基盤として利用
|
||
*
|
||
* ## 🛠️ 利用可能メソッド
|
||
* ### TCP Server
|
||
* - `bind(address, port)` - TCP ソケット bind
|
||
* - `listen(backlog)` - 接続待機開始
|
||
* - `accept()` - クライアント接続受諾
|
||
*
|
||
* ### TCP Client
|
||
* - `connect(address, port)` - サーバーへ接続
|
||
*
|
||
* ### IO Operations
|
||
* - `read()` - データ読み取り
|
||
* - `write(data)` - データ送信
|
||
* - `close()` - ソケット閉鎖
|
||
*
|
||
* ## 💡 使用例
|
||
* ```nyash
|
||
* // TCP Server
|
||
* server = new SocketBox()
|
||
* server.bind("0.0.0.0", 8080)
|
||
* server.listen(128)
|
||
* client = server.accept()
|
||
*
|
||
* // TCP Client
|
||
* client = new SocketBox()
|
||
* client.connect("127.0.0.1", 8080)
|
||
* client.write("Hello Server!")
|
||
* response = client.read()
|
||
* ```
