类：WASI

【Class: WASI】

WASI 类提供了 WASI 系统调用 API 以及用于处理基于 WASI 的应用的额外便捷方法。每个 WASI 实例代表一个独立的沙箱环境。出于安全考虑，每个 WASI 实例必须显式配置其命令行参数、环境变量和沙箱目录结构。

【The WASI class provides the WASI system call API and additional convenience methods for working with WASI-based applications. Each WASI instance represents a distinct sandbox environment. For security purposes, each WASI instance must have its command-line arguments, environment variables, and sandbox directory structure configured explicitly.】
