An implementation of union-find / congruence-closure in Rust. Forked from rustc for independent experimentation. My intention is to iterate and improve this code and gradually bring back changes into rustc itself, but also to enable other crates.io packages to use the same code.
The name "ena" comes from the Greek word for "one".
Like rustc itself, this code is dual-licensed under the MIT and Apache licenses. Pull requests, comments, and other contributions are assumed to imply consent to those terms. Moreover, it is understood that any changes here may well be used in rustc itself under the same terms.
