Is it wrong to expect being able to implement standard data structures such as doubly-linked lists and trees with back-pointers having known complexity and performance trade-offs in a language advertising itself as replacement for a system programming language? After all, you should be able to implement standard libs in the language itself, and also to replace existing implementations.

It is wrong to expect it to be something that you start to learn the language with. Non-beginners write data structures in Rust just fine.
