Have anybody implemented anything near the expressiveness and ease of use of Rust's builtin benchmarking features

https://doc.rust-lang.org/1.16.0/book/benchmark-tests.html

I'm mostly interested in completely automatic printing of results such as

test tests::bench_add_two ... bench:         1 ns/iter (+/- 0)

and letting the benchmarking library (like in Rust) itself figure out the suitable number of iterations a function should be tested based on some heuristics on how long one iteration takes and some default upper wall clock time limit.

Perhaps https://dlang.org/phobos/std_datetime_stopwatch.html#benchmark ?

That fulfils neither of my two requirements mentioned in above; it requires explicit iteration count given by the caller and no automatic printing of results.
