Thanks, that would be a valid approach and my last resort.

As you said, I hope someone knows a more elegant solution, though!

Golangs web server is production grade and used in production. (Of course everyone uses some high performance proxy like NGINX for serving static pages, that’s another story.)

Technically you are right that java has no production web server, which I don’t like, OTOH Java has standard APIs WebServers and Spring is the defacto standard for web applications. (I totally would not mind to move Spring into the OpenJDK.)

My point is simple: Instead of having Rust edtion 2020, 2021 etc. and tweaking the syntax ad infinitum, I’d rather have a community which invests in a good/broad standard library and good tooling.

The only platform widely used in production w/o a big standard library is Node.js/JavaScript, mostly for historical reasons and look at the problems that Node.js has for a decade now because of the missing standard library.

Easily, just look at the standard libraries of Java/Python and Golang! :-P

To get one thing out of the way: Each standard library has dark corners with bad APIs and outdated modules. IMHO it is a tradeoff, and from my experience even a bad standard library works better than everyone reinvents their small module. If you want to compare it to human languages: Having no standard library is like agreeing on the English grammar, but everyone mostly makes up their own words, which makes communication challenging.

My examples of missing items from the Rust standard library (correct me, if I am wrong, not a Rust user for many reasons):

• Cross platform GUI library (see SWING/Tk)
• Enough bits to create a server
• Full set of data structures and algorithms
• Full set of serialization format processing XML/JSON/YAML/CVS/INI files
• HTTP(S) server for production with support for letsencrypt etc.

Things I don’t know about if they are provided by a Rust standard library:

• Go like communication channels
• High level parallelism constructs (like Tokyo etc.)

My point is, to provide good enough defaults in a standard library which everybody knows/are well documented and taught. If someone has special needs, they always can come up with a library. Further, if something in the standard library gets obsolete, it can easily be deprecated.

THIS.

I do not get why people don’t learn from Node/NPM: If your language has no exhaustive standard library the community ends up reinventing the wheel and each real world program has hundreds of dependencies (or thousands).

Instead of throwing new features at Rust the maintainers should focus on growing a trusted standard library and improve tooling, but that is less fun I assume.
