> I would much rather be able to grep for `unsafe {}` and audit parts of a trie-map for memory safety, as opposed to auditing my entire program for memory safety violations. you mean auditing the entire implementation of the trie data structure, not the entire program. Guess what? In rust, if you use unsafe, you also have to audit the implementation of the entire trie datastructure. And if you think you don't, then I submit you don't understand Rust safety that well.
