# wasm_test

#### 介绍
对wasm之wasmtime进行各种测试学习

#### use_wasm_in_rust
尝试在自己的rust项目中调用外部wasm文件（.wat: wasm text format file;.wasm: wasm binary format file）

#### wasm之wasmtime wasm32-wasi外部链接

#### [use WebAssembly in Rust](https://docs.wasmtime.dev/lang-rust.html)

#### [write WebAssembly by Rust](https://docs.wasmtime.dev/wasm-rust.html)

源码见工程[write_wasm_by_rust](https://gitee.com/wasmtime/wasm_test/tree/master/write_wasm_by_rust)

编译前准备：
1. 安装wasmtime: 
    curl https://wasmtime.dev/install.sh -sSf | bash
    source ~/.bashrc
2. rust增加target wasm32-wasi: 
    rustup target add wasm32-wasi
3. 进入rust工程目录：

    binary project: write_wasm_by_rust/just_hello_wasm

        cargo build --target=wasm32-wasi

        ls target/wasm32-wasi/debug/just_hello_wasm.wasm

        wasmtime target/wasm32-wasi/debug/just_hello_wasm.wasm

    cdylib project: write_wasm_by_rust/just_hello_wasm_lib

        cargo wasi build

        ls target/wasm32-wasi/debug/just_hello_wasm_lib.wasm

        wasmtime --invoke print_hello target/wasm32-wasi/debug/just_hello_wasm_lib.wasm
