execution duration

In Rust, you can measure the execution duration of your code by using the std::time::Instant module. The Instant struct provides a way to create a timestamp at a specific point in time, which allows you to calculate the duration between two timestamps.

Here is an example of how you can measure the execution duration of a specific code block in Rust:

use std::time::Instant;

fn main() {
    let start = Instant::now();

    // Your code block here

    let duration = start.elapsed();

    println!("Execution duration: {:?}", duration);
}

In this example, the Instant::now() function creates a timestamp at the beginning of the code block you want to measure. Then, after the code block has executed, the start.elapsed() function calculates the duration between the start timestamp and the current time. Finally, the duration is printed using println!.

Keep in mind that the execution duration measured by this method includes any overhead from the operating system and other external factors. It's also important to note that the resolution of the timer used by Instant may vary depending on the platform you are running your code on.
