True. Not widely available though. The great thing about Rust is that has a whole of the advantages of Haskell, and C++, and to a lesser extent even languages like Python.
Haskell has been around for more than a decade and had huge uptake by language nerds, but the only significant OSS written in it is Pandoc. In contrast, Rust already has Servo and a number of CLI tools, ripgrep being the most prominent.
I'm not sure what you consider 'significant', but to my mind, there are many great haskell open source projects: xmonad, shellcheck, stack, haxl, to name a few.
Not to mention how many languages are written in it: Elm, Purescript, Idris, GHC itself.
I almost listed xmonad. I haven’t heard of the other ones. Doesn’t change my point.
Leaving popularity contests aside, i worked in a company using Haskell and i did used a lot these techniques, if that counts \o/
i guess today it only matter how many stars you repo has in github...
At the same level of performance though?
If you are asking if it's fast? yes it's fast serialization. Not sure which numbers you have at hand, but for me fast means it isn't the bottleneck of my application.
it doesn't have to be to make the point, as Serde isn't on the same level of verbosity as Aeson.
