Cargo的`cargo build`命令编译项目并生成二进制文件，若仅需编译项目不生成二进制文件，使用`cargo check`。运行项目使用`cargo run`。Cargo提供多种命令，常用指令包括new、build、run、check等。更多指令可通过`cargo --help`查看。自定义扩展指令使项目更具灵活性。依赖管理在Rust项目中至关重要。通过...

Some of my custom targets require me to enable build-std, which currently I can enable through .cargo/config.toml [unstable] build-std = ["core"] but this means it is enabled for every target. However I don't necessarily want it for buil...
Problem Short version: I am writing an application for a slightly unusual embedded platform, which entails using a platform json and no-std. It worked great until I decided I wanted to write a #[test] function for one of my files. At thi...
It looks like cargo does both a regular build as well as a check build of several crates for some reason. Do you have build-std in .cargo/config.toml or something? Yes, here is myconfig.toml: [unstable]build-std= ["core","compiler_builtins","alloc"]build-std-features= ["compiler-...
