By default, cargo new creates a binary (application) template. You can use --bin flag to explicitly specify it.

cd hello-world
cargo run

Tip

Run cargo run --help or cargo help run to see detailed options of cargo run command.

cargo run compiles/builds the code and then run the resultant executable all in one command.
