Rust standard library is dramatically more useful than C’s. C doesn’t offer any kind of collections in its libraries. Every C project just grows its own differe

  Compared to C++, Rust's libraries are severely anemic, especially in the areas where C++ is strong at such as collections, algorithms, and metaprogramming constructs such as type traits. Rust's standard library is better than C in certain areas–you identified one, which is dictionaries. (Linked lists are hard to provide a useful, performant API for; it's often better to roll your own–especially in C–than rely on a library to do it for you.) But even without including C's POSIX libraries, Rust seems to be missing things like random number generation. I general, yes, I would probably say that I would prefer Rust's standard library over C's, but it's not huge in any sense and much closer to C's than C++'s. In any case, I came into Rust thinking it would be like C++, and ergonomically it certainly is. But its standard library is nothing like C++'s and this caused me disconcertion until I began treating it like C's, and being happy whenever it provided me anything beyond that rather than disappointed whenever it was missing something I found useful.
