rust armanriazi unwrap

The unwrap function in Rust is used to extract the value from a Result type. It returns the value if the Result is Ok, and panics if the Result is Err. Here's an example of how to use unwrap:

fn main() {
    let result: Result<i32, &str> = Ok(5);
    let value = result.unwrap();
    println!("The value is: {}", value);
}

In this example, result is an Ok variant with a value of 5. The unwrap function is called on result to extract the value, which is then assigned to the variable value. Finally, the value is printed using println!.

It's important to note that using unwrap can be risky because it will panic if the Result is Err. It's generally recommended to handle the Result in a more robust way, such as using match or unwrap_or_else to handle the Err case.
