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.

What is a PPA and how do I add one to Ubuntu?
Jun 18, 2025 am 12:21 AM
PPA is an important tool for Ubuntu users to expand their software sources. 1. When searching for PPA, you should visit Launchpad.net, confirm the official PPA in the project official website or document, and read the description and user comments to ensure its security and maintenance status; 2. Add PPA to use the terminal command sudoadd-apt-repositoryppa:/, and then run sudoaptupdate to update the package list; 3. Manage PPAs to view the added list through the grep command, use the --remove parameter to remove or manually delete the .list file to avoid problems caused by incompatibility or stopping updates; 4. Use PPA to weigh the necessity and prioritize the situations that the official does not provide or require a new version of the software.

How to create a file of a specific size for testing?
Jun 17, 2025 am 09:23 AM
How to quickly generate test files of a specified size? It can be achieved using command line tools or graphical software. On Windows, you can use fsutilfilecreatenew file name size to generate a file with a specified byte; macOS/Linux can use ddif=/dev/zeroof=filebs=1Mcount=100 to generate real data files, or use truncate-s100M files to quickly create sparse files. If you are not familiar with the command line, you can choose FSUtilGUI, DummyFileGenerator and other tool software. Notes include: pay attention to file system limitations (such as FAT32 file size upper limit), avoid overwriting existing files, and some programs may

How to install Linux alongside Windows (dual boot)?
Jun 18, 2025 am 12:19 AM
The key to installing dual systems in Linux and Windows is partitioning and boot settings. 1. Preparation includes backing up data and compressing existing partitions to make space; 2. Use Ventoy or Rufus to make Linux boot USB disk, recommend Ubuntu; 3. Select "Coexist with other systems" or manually partition during installation (/at least 20GB, /home remaining space, swap optional); 4. Check the installation of third-party drivers to avoid hardware problems; 5. If you do not enter the Grub boot menu after installation, you can use boot-repair to repair the boot or adjust the BIOS startup sequence. As long as the steps are clear and the operation is done properly, the whole process is not complicated.
