cargo new hello_cargo
Creating binary (application) `hello_cargo` package note: see more `Cargo.toml` keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
This command creates a folder with the name of the new project containing a src directory and the dependency file called Cargo.toml.

It has also initialized a new Git repository along with a .gitignore file. Git files won’t be generated if you run cargo new within an existing Git repository; you can override this behavior by using cargo new --vcs=git.
