I started writing benchmarks in Rust with "bench" and Rust nightly as written in the docs.
In order to share the code between test and benchmarks i've added Option<&mut Bencher>
and either run the code block directly or with bencher passed ("src/lib.rs"):
fn block_requests(bencher_option: Option<&mut Bencher>, ...) {
...
let mut block = || {
... // shared
}
match bencher_option {
// regular test
None => block(),
// benchmark
Some(bencher) => {
bencher.iter(block);
}
}
...
}
// call from test
#[test]
fn test_smth() {
block_requests(None, &requests, &mut matcher);
}
// call from benchmark
#[bench]
fn bench_smth(b: &mut Bencher) {
block_requests(Some(b), &requests, &mut matcher);
}
Now i want to use Rust stable for benchmarks. Since "bencher" crate is not updated for 3 years it seems that "criterion" crate is the default option. For this i have to move the code to "./benches/my_benchmark.rs".
How can i still share the block_requests(..)
between the tests and benchmarks?
