Lender

This is just my own personal Rust practice, trying to implement a lending iterator.

Check out the [lending-iterator] crate, by the great Daniel Henry-Mantilla, for a full implementation of lending iterators (with the 'higher-kinded type' workaround/bug). The [streaming-iterator] crate is also a great crate if you only need to iterate over a reference to an item.

Turn a lender into an iterator with cloned() where lend is Clone, copied() where lend is Copy, owned() where lend is ToOwned, or iter() where lend is already owned.

Neither partition_in_place or array_chunks is supported by lending iterators.

Resources

I couldn't have even hoped to begin trying to use this problem as practice without relying on help from the following people and resources, please check them out:

• Sabrina Jewson's Blog for their awesome blog post on why lifetime GATs are not (yet) the solution to this problem, I highly recommend reading it.
• @vague, Cole Miller, and awesome people on the Rust Users Forum in helping me understand the borrow checker and HRTBs better and being patient with me and other aspiring rustaceans as we try to learn more about Rust.
• Daniel Henry-Mantilla by writing [lending-iterator] and many other great crates and being a great teacher.
• Finally, it goes without saying, everyone who's contributed to Rust core library for making such a great language and iterator library.

Unsafe & Transmutes Beware!!!

Many patterns in lending iterators require polonius-emulating unsafe code, but please, if you see any unsafe code that can be made safe, please let me know! I am still learning Rust and I'm sure I've made many mistakes.
