how to check for os in rust

To check for the operating system in Rust, you can use the std::env::consts::OS constant. This constant returns a string representing the current operating system. Here's an example:

fn main() {
    let os = std::env::consts::OS;
    println!("Operating System: {}", os);
}

This code will print the current operating system. For example, if you are running the code on a Windows machine, it will print "windows". If you are running it on a Linux machine, it will print "linux". And if you are running it on a macOS machine, it will print "macos".

Please note that the std::env::consts::OS constant is part of the Rust standard library, so you don't need to import any additional crates to use it.

I hope this helps! Let me know if you have any further questions.
