@benchmark

All lessons are open — jump whenever you need.

@benchmark measures execution time:

@benchmark
fn heavy_computation() -> int {
    let mut sum = 0
    for i in 0..1000000 {
        sum = sum + i
    }
    return sum
}

print(heavy_computation())
// [benchmark] heavy_computation: 12ms

Goal: Add @benchmark to a function that computes the sum from 1 to 1,000,000.
