Install Rustup (Rust installer and version management tool) on Mac:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

When you install Rustup you’ll also get the latest stable version of the Rust build tool and package manager, also known as Cargo. Cargo does lots of things:

• build your project with cargo build
• run your project with cargo run
• test your project with cargo test
• build documentation for your project with cargo doc
• publish a library to crates.io with cargo publish

To test that you have Rust and Cargo installed, you can run this in your terminal of choice:

cargo --version

Rust updates very frequently. Get the latest version of Rust by running:

rustup update

Rust programming language

All of good ideas from the world of programming language design combine in a unique way to make Rust a language that truly makes you think about writing code from a novel perspective. It does not matter how much experience you have, learning Rust will forever change the way you write code for the better.

There is no best programming language. Almost every task has a variety of languages which could be the right tool. Every language comes with good parts and bad parts. Evaluating these trade-offs when faced with a particular problem is an art.

Rust isn't limited to low-level systems programming. It’s expressive and ergonomic enough to make CLI apps, web servers, and many other kinds of code quite pleasant to write

Language features

There are a lot of features of Rust which make it a great tool for a great number of tasks. Some highlights include:

• Performance
• Strong, static, expressive type system
• Great error messages
• Modern generics
• Memory safety
• Fearless concurrency
• Cross platform
• C interoperability

Performance

Rust is exceptionally fast, as C and C++. Memory consumption - rust does not have a garbage collector so you can use exactly as much memory as is strictly necessary at any given time.

Rust uses a relatively unique memory management approach that incorporates the idea of memory "ownership". Basically, Rust keeps track of who can read and write to memory. It knows when the program is using memory and immediately frees the memory once it is no longer needed. It enforces memory rules at compile time, making it virtually impossible to have runtime memory bugs. You do not need to manually keep track of memory. The compiler takes care of it.

Cargo

Cargo is the Rust package manager. Cargo downloads your Rust package's dependencies, compiles your packages, makes distributable packages, and uploads them to crates.io, the Rust community’s package registry.

Some Cargo commands:

• cargo --version
• cargo new hello_cargo - create a new project called hello_cargo
• cargo build - create an executable file in target/debug/hello_cargo (the default build is a debug build)
• ./target/debug/hello_cargo # or .\target\debug\hello_cargo.exe on Windows - runs the executable
• cargo run - one command to compile and run the executable - using cargo run is more convenient than remembering to run cargo build and then use the whole path to the binary
• cargo check - build a project without producing a binary to check for errors
• cargo build --release - compile with optimizations, creates an executable in target/release
  If you’re benchmarking your code’s running time, be sure to run cargo build --release and benchmark with the executable in target/release.
