Introduction to Rust

Rust (rust-lang) is a modern, high-performance, systems programming language known for its speed, safety, and concurrency features. It offers high-level abstractions while maintaining performance comparable to C/C . Key features include:

• Zero-cost abstractions: Abstractions don't impact runtime performance.
• Move semantics: Efficient data ownership management.
• Guaranteed memory safety: Prevents memory errors like dangling pointers and leaks.
• Thread safety: Prevents data races in concurrent programming.
• Trait-based generics: Flexible code reuse.
• Pattern matching: Concise and expressive code.
• Type inference: Reduces explicit type declarations.
• Minimal runtime: Enhanced performance due to lack of garbage collection.
• Efficient C bindings: Easy integration with C libraries.

Rust is used in production by many organizations, including Mozilla, Dropbox, and Amazon.

Installing Rust on Linux

The recommended installation method is using rustup, the official Rust toolchain installer. Open your terminal and execute:

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

or

curl https://sh.rustup.rs -sSf | sh

Select option 1 for default installation or 2 for customization. The installer will download the compiler, Cargo (the package manager), and add necessary commands to your PATH. Source the environment file (e.g., source $HOME/.cargo/env) to activate the changes. Verify installation with:

rustc --version

Building a Simple Rust Program

Create a project directory (e.g., my_rust_projects). Use Cargo to create a new project:

cargo new hello_world
cd hello_world
cargo run

This compiles and runs a basic "Hello, world!" program. Alternatively, manually create a file (e.g., ostechnix.rs) with the following code:

fn main() {
    println!("Hello, Welcome To OSTechNix blog!");
}

Compile and run it using:

rustc ostechnix.rs
./ostechnix

Troubleshooting

If you encounter a "linker cc not found" error, install a C compiler (like GCC).

Enabling Tab Completion

Rustup supports tab completion for various shells. Follow the instructions for your shell (Bash, Fish, Zsh) in the original document to enable this feature.

Updating Rust

To update to the latest version:

rustup update

Use rustup self update to update rustup only.

Uninstalling Rust

To uninstall:

rustup self uninstall

This removes Rust and reverts PATH changes. Remember to delete your project directory.
