Peach Profiler in action

use peach_profiler::{time_block, time_main, time_function};

// Add the `time_main` macro to the main function
#[time_main]
fn main() {
    let answer = {
        // Time a block
        time_block!("answer_block");

        fibonacci(22)
    };

    println!("{answer}");
}

// Time a function
#[time_function]
fn fibonacci(x: usize) -> usize {
    if x == 0 || x == 1 {
        return 1;
    }

    fibonacci(x - 1) + fibonacci(x - 2)
}
