Benchmarking programs in Rust

Question

How is it possible to benchmark programs in Rust? For example, how would I get execution time of program in seconds?

Answer 1

I created a small crate for this (measure_time), which logs or prints the time until end of scope.

#[macro_use]
extern crate measure_time;
fn main() {
    print_time!("measure function");
    do_stuff();
}
