You can create a new project via
cargo new hello_cargo
This created a new Git project with its respective .gitignore if we're not in one yet.
We can then add code in the src/ folder. Afterwards we can compile the code in one go
using
cargo run
To check if the code compiles without creating the executable we can use
cargo check
This is much faster so it's useful during development. Finally, we can compile the code with optimizations by running
cargo build --release
The executables are inside the target/release/ folder.
The presence of ! in println! signals that it's a Rust macro instead of a
normal function.
Formatting can be done via the rustfmt
tool. This can be configured as to autoformat on VSCode.
