> Rust had a lot community content, but not a comprehensive stdlib; last checked 3-4 years ago

Still the case now (depending on your definition of ‘comprehensive’ of course). It’s an explicit non-goal of Rust to include “everything” (eg. http, crypto, random numbers) in std because of the stability promises - you can’t make breaking changes to std unless you’re fixing a soundness issue AFAIR.

I was evaluating Rust for some cryptography use case and there were only "random" community libs available that lacked support here and there. And I actually had no trust in any of those libs.

A stdlib must not contain everything but a solid cryptography lib is probably a good idea.

Looks like the situation improved a bit: https://cryptography.rs/

I would still like to have a more comprehensive or high level stdlib for Rust that is maintained by a core Rust team.
