> C programmers tend to write their data structures themselves. Rust programmers tend to use packages. If you've determined that you need a linked list in Rust, you don't start writing one: you "use std::collections::LinkedList;". It's a doubly-linked one, so maybe that's not what you need. In that case, you go on crates.io and see if someone has already written what you need. (225 hits incidentally: https://crates.io/search?q=linked%20list)

Not sure why you bring this up, since sooner/later people are going to need to implement their own data-structures(and this ownership problem will surface) and being it harder to implement is not relevant to package management(after all somebody did just implement that and made it available).
