$ cargo new hello_world Cargo defaults to --bin to make a binary program. To make a library, we would pass --lib, instead. Let’s check out what Cargo has generated for us: $ cd hello_world $ tree . . ├── Cargo.toml └── src └── main.rs 1 directory, 2 files This is all we need to get started. First, let’s check out Cargo.toml:
json-render-diagnostics: Instruct Cargo to not include rustc diagnostics in JSON messages printed, but instead Cargo itself should render the JSON diagnostics coming from rustc.

Whenever a dependency from a git repository is specified without any other specifiers (namely via the properties revtagbranchcargo update
cargo update

I tried to use this command:
cargo install rust_wheel --force
That is the wrong Cargo command. cargo install
Also tried
.cargo update rust_wheel
Wrong syntax. To issue an update of a specific dependency, use the -p
cargo update -p rust_wheel
