This is long with a lot of detail, but to me the key bit of information is: iterators (as expressed by Rust's Iterator trait) have some noticeable drawbacks. Notably, you can't delete while iterating. However, a different abstraction called Cursors can accommodate this. I asked recently: "does this mean iterators are broken, or are iterators vs. cursors more of a fundamental tradeoff?"
