How to change event-loop lib in vibed?

Question

I need to change event-loop in vibed. Docs says that "vibe.d has always used libevent under the hood by default" and "libasync is a cross-platform event loop library written completely in D".

How I can change libevent to libasync?

I found example of dub.json config, but how I can set it in dub.sdl?

upd: it's seems that versions "libasync" is working.

you should put your answer as an answer and accept it yourself if it works — Adam D. Ruppe, Sep 01 '17 at 20:18
Adam, I am not still sure that `libasync` now is used. How to check it? — Dmitry Bubnenkov, Sep 02 '17 at 16:52
Check with the `ldd` command on Linux and see what lib it linked if it is dynamic. Otherwise, `dub -v` and inspect what the dmd command line is. — Adam D. Ruppe, Sep 02 '17 at 20:36

If you want to use built-in libasync support in vibe-d, add the following to your dub.json:

"dependencies": {
    "vibe-d": ">=0.8.1"
},
"subConfigurations": { 
    "vibe-d": "libasync" 
}

If you prefer SDL, your dub.sdl file should contain something like:

dependency "vibe-d" version=">=0.8.1"
subConfiguration "vibe-d" "libasync"

Could you give solution for `.sdl`? – Dmitry Bubnenkov Sep 02 '17 at 16:50
is `subConfiguration` section necessary? Does it's equal to `versions "libasync"` ? – Dmitry Bubnenkov Sep 03 '17 at 08:25
I tried with and without `subConfiguration "vibe-d" "libasync"` and got binary of the same size... – Dmitry Bubnenkov Sep 04 '17 at 07:34
