Crate udf

Version note: Because of reliance on a feature called GATs, this library requires Rust version >= 1.65 which is currently in beta. If rustup show does not show 1.65 or greater under active toolchain, you will need to update:

rustup default beta
rustup update beta

1.65 is scheduled to become stable on November 03 2022 UTC, so this message may not be relevant not long after time of writing.
