bindgen主要用来实现rust代码对c接口的单向调用;CXX工具可以实现rust和C++的互相调用。 基于cargo的构建 对于由Cargo的构建,需要使用一个构建脚本来运行CXX的C++代码生成器。 典型的构建脚本如下: # Cargo.toml[build-dependencies]CXX-build="1.0" // build.rsfnmain()
说Rust之前,先说下go,因为go比较简单,而且也支持函数类型,写起来有点像c里面的写法,同样可以在结构体里面放置函数指针。 import "fmt" func StdLog(s *Student) { fmt.Printf("学生(%s) {姓名:[%s], 年龄:[%d]}\n", s.Id, s.Name, s.Age) } type Student struct { Id string Age uint Name st...
Writing an extension gem (calling Rust from Ruby) Ruby extensions must be built as dynamic system libraries, this can be done by setting the crate-type attribute in your Cargo.toml. Cargo.toml [lib] crate-type = ["cdylib"] [dependencies] magnus = "0.7" When Ruby loads your extension it...

rust不允许, let a=1,b=1; 这样定义变量(c/c++/js风格) 也不允许 let a,b=4,1; 这样定义变量, (lua风格) 在这里其实'a 和 'b的生命周期 在编译器看来是不一样的,这一点一定要记住。 但是可以调用同一生命周期的函数,因为 'b生命周期包含'a 生命周期。 编译器处理其实是按照'a生命周期(公共的部分...

In short, it makes C/C++, Rust, C#* run in a web browser. It is designed to run alongside JavaScript. WebAssembly is an open web standard and it is supported in (most) web browsers. Those browsers who support it, all major browsers, supports it without plugins. This article will demo...
