Wasmtime：开源的轻量级 WebAssembly 运行时
Wasmtime is a standalone runtime for WebAssembly, WASI, and the Component Model by the Bytecode Alliance.
WebAssembly (abbreviated Wasm) is a binary instruction format that is designed to be a portable compilation target for programming languages. Wasm binaries typically have a .wasm file extension. In this documentation, we'll also use the textual representation of the binary files, which have a .wat file extension.
