The following code will not compile just yet. Variables in Rust are defined using the let keyword and are immutable by default. The optimizations make your Rust code run much much faster but with a small penalty in compilation time. This command will create an executable inside target/release instead of target/debug. When you are ready to build the final executable, you can use the command cargo build -release to compile it with optimizations. You don’t have to use cargo to compile and run Rust programs, but it is a very friendly tool and I highly recommend using it. This executable will be stored in target/debug . You can use cargo run to run the main file in debugging mode or cargo build to create an executable. In order to run the program, you have a few different options using Cargo. The file main.rs is the entry point of the program. When you are inside the folder that you want to place the project, simply use cargo new rusty_cli.Ĭargo will work its magic and create a project structure that it understands, including a folder called src, and inside will be a file called main.rs. Then “cd” yourself to that location in the cmd/terminal. Say you want to create a project called “rusty_cli”.įind a location on your file system where you want to place your project. When you have installed Rust and its fantastic package manager called Cargo, you are good to go. You can install Rust by following the instructions here or by just Googling. The installation of Rust is painless thanks to a little nifty cli called rustup. You just need to think a little differently when coding - like a Rustacean! Installation and First Project Rust has gotten a reputation of being hard to learn, but I think that it really comes down to the initial approach and mindset. In return, you get safety and mind-blowing speed. Rust is a systems programming language that runs blazingly fast, prevents almost all crashes, and eliminates data races.Įven though Rust is classified as a systems programming language, you can really build anything in Rust. Rust is here to stay and if you want to learn a performant and modern language that is both safe and future-proof, Rust is a good choice.
