Rust Language Learning material

Rust

• Rust is blazingly fast systems programming language that prevents segfaults and guarantees thread safety.
• Originally Rust was designed by Graydon Hoare, Now it managed by Rust project developers.
• The first version of Rust was released in the year 2010.
• Rust is syntactically similar to C++.

Rust Features

• zero-cost abstractions
• move semantics
• guaranteed memory safety
• threads without data races
• trait-based generics
• pattern matching
• type inference
• minimal runtime
• efficient C bindings

Rust's Garbage Collector

• Rust uses a static garbage collector.
• It works on the principle of automatic memory management which means it automatically recycles the memory that will not be used again.

Companies Using Rust

• 360dialog
• OneSignal
• Coursera
• Atlassian
• Braintree
• npm, Inc
• Mozilla
• Academia.edu
• Xero

Cargo

• It's a build system and package manager built for Rust users to manager projects in it.
• The Cargo system manages three things for users, building code, downloading the libraries, and rebuilding those libraries.

Cargo.lock

• When a user runs cargo build command it automatically creates a file named as Cargo.lock to keep track of dependencies in the user application.

Cargo Commands

cargo new
cargo build
    cross compilation to linux is achieved by running
            cargo build --target x86_64-unknown-linux-musl
    To cross compile to a static Linux binary, install
            rust-std-linux

cargo test
cargo run
cargo fmt
cargo clippy
cargo vendor

Rust Modules

• Tokio : Asynchronous run-time for Rust
• Hyper : fast, safe HTTP implementation written in and for Rust
• Tower : Library for modular and reusable components for building robust networking clients & servers.

Installation

1. Linux

This repository contains learning material for Rust. The examples and runnable demos are located in the 00_Demo/ folder (a small Cargo project).

Install Rust using the recommended rustup tool. These steps work on most Linux distributions.

1. Install rustup (official installer):

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

Follow the interactive prompt (choose the default 'stable' toolchain). After installation, reload your shell or run:

source "$HOME/.cargo/env"

2. Verify Rust and Cargo are installed:

rustc --version
cargo --version

3. Install recommended developer tools used in this repo (optional but useful):

rustup component add rustfmt clippy rust-src
cargo install cargo-edit cargo-watch

4. Run the demo examples (from repository root):

cd 00_Demo
cargo run --bin hello_world

Notes:

• The 00_Demo/ directory is a standalone Cargo crate containing multiple example binaries in 00_Demo/src/bin/.
• Use cargo run --bin <name> to execute a specific example, or cargo build --release to produce optimized artifacts.
