Cargo Example

cargo new osinfo

cd osinfo

Replace the main.rs code with the code given below

// Rust sample for displaying OS Info

fn main() {
    println!("Hello, world!");

    let info = os_info::get();

    // Print full information:
    println!("OS information: {}", info);

    // Print information separately:
    println!("Type: {}", info.os_type());
    println!("Version: {}", info.version());
    println!("Bitness: {}", info.bitness());
}

cargo build

Script will fail to build.

Find out the correct crate from crates.io and add it.

Run the following statements

cargo check

cargo fetch

cargo build

check the executable under target/debug

cargo build --release

check the executable under target/release

The release executable will be smaller in size than debug executable.

Because, debug contains symbols & backtraces
