Rust中的Cargo构建、运行、调试

#创建—个普通的项目：
cargo new project_name --bin 
#创建一个库cargo build
cargo new lib_name --lib--vcs none
#构建编译，默认会编译到target/debug/project_name下
cargo build
#运行
cargo run
#构建编译发布版本，这会做很多优化，并编译到target/release/project_name下
cargo build --release
#如果你想修改cargo .lock文件的话，运行它
cargo update
#如果你只是想更新rand版本的话，运行它
cargo update-p rand
#运行test测试
cargo test abc
#检查代码，确保能通过编译，但不产生执行文件其速度比cargo build快得多编写代码时可以反复的使用cargo check检查代码，提高效率。
cargo check
