Just out of curiosity, didn't you do a google-search for "linked list in Rust" when you ran into problems? Or isn't that your style? :)

Anyway, thanks for the thought-provoking post.

I did. I found the book of linked lists at the bottom of the post. After reading and appreciating the complexity I didn't want to deal with, I just wrote it in Go

No jugement here, but I curious to understand your situation: if you didn't want to deal with the complexity of the implementation, why didn't you just import a linked list from the standard library ? Did you just want to implement a linked list for learning, but still put the minimum effort in the process ?

The standard library linked list doesn't support inserting in the middle
