Rust has a really big and comprehensive stdlib, especially compared to languages like C or JavaScript. It just decided that certain things won't be solved in the standard lib because there is no obviously-right solution and evolving towards a good solution is much easier in packages than in the stdlib, because the stdlib isn't versioned.

Some of the gaps feel huge, like no random, no time/date handling, and no async runtime. But but for most of them there are canonical packages that 95% of the ecosystem uses, with a huge amount of eyeballs on them. And sometimes a better solution does emerge, like jiff slowly replacing chrono and time for time/date handling.

Obviously this isn't the best solution from a security perspective. There would be less potential for supply chain attacks if everything was in the standard library. But that has to be weighed against the long-term usability of the language
