This PR introduces ordered map data structures, namely `DTreeMap`, `TreeMap`, `TreeSet` and their `.Raw` variants, into the standard library. There are still some operations missing that the hash map has. As of now, the operations are unverified, but the corresponding lemmas will follow in subsequent PRs. While the tree map has already been optimized, more micro-optimization will follow as soon as the new code generator is ready. --------- Co-authored-by: Paul Reichert <6992158+datokrat@users.noreply.github.com> |
