Rust Usage with Cargo

Prerequisites

Before proceeding, ensure the following are installed and set up:

1. Rust Toolchain: Install Rust using rustup.
2. filerix: Ensure the filerix library and its development files are installed.

Installing Dependencies

Depending on your distribution, install Rust and the required build tools:

Fedora

sudo dnf install cargo rustc

Ubuntu

sudo apt install cargo rustc

Arch

sudo pacman -Syu cargo rust

Creating a Rust Project

1. Create a new Rust project:

   cargo new example  
   cd example

2. Add filerix to your Cargo.toml:

   [dependencies]  
   filerix = "0.1"

Building the Example

1. Compile the project with Cargo:

   cargo build --release

   This will generate the executable in target/release/example.

Running the Example

1. Run the compiled binary:

   ./target/release/example

2. The example will fetch and log the disk usage information for the specified path (/ by default). You should see output like this:

   Used space: <used_bytes> bytes  
   Total space: <total_bytes> bytes

Understanding the Code

The Rust code interacts with the filerix library to fetch the disk usage of a given directory (/ by default). Here’s a quick breakdown of the key components:

• get_drive_usage(): Retrieves the disk usage details (used space and total space) for the given path.
• println!: Prints the result to the console.

This example demonstrates how to use filerix for filesystem operations and integrate it into a Rust project with Cargo.

Common issues

• If you encounter issues with library loading (e.g., filerix.so not found), ensure the library path is correctly set:

  export LD_LIBRARY_PATH=/usr/local/lib64:$LD_LIBRARY_PATH
