This will summarize all key concept I will encounter when reading this book. I decided to maintain this repository because I found rust very interesting, it is different from every programming language I have ever tried. I this this learning experience will be a lot of fun
Rustup is the installer for the rust programming language, it is like nvm for those are used to Javascript
- On macOS and Linux can be installed via this script:
curl https://sh.rustup.rs -sSf | sh - On windows you can install it by downloading and running this exe file
After installation Rust toolchain can be upgraded by using the following
command: rustup update
To uninstall Rust and rustup: rustup self uninstall
To compile a Rust program we can use rustc main.rs this will create a
executable file that can be run
Cargo is Rust's build system and packet manager, creating a new project with
it is very simple cargo new <app_name> --bin or cargo new <lib_name> --lib
cargo runruns the program without create the executablecargo buildbuild an executable (debug mode) that you can run latercargo build --releasebuild an executable (release mode) that you can run latercargo checkcheck only if the program compilescargo upgradewhen in Cargo.toml you update a dependency run thiscargo doc --opengenerate the doc for your crate so you can check which method call
Guessing game chapter was a pretty fun experience where I learned a lot, for example
- Declaring variables with
let - Declaring mutable variables with
let mut - Use an external crate
usekeyword - Compare two variables
guess.cmp(&secret_number), remember to importstd::cmp::Orderingbecause needed - Parse a String to another type
let guess: u32 = guess.trim().parse(), remember type annotation is needed - Use shadowing to take the same variable name (ex after parsing) we don't need to define other variables like guess_int
- match is like switch but doesn't need default or break because it doesn't fall through
