I'm not sure I've ever seen something like that

[apasel422]

Java has it: http://docs.oracle.com/javase/8/docs/api/java/util/LinkedHashSet.html.

[Gankra]

Whelp, all right.

[apasel422]

Where should this type live? linked_hash_map::LinkedHashSet?

[Gankra]

It needs a seperate module for iterators.

[apasel422]

linked_hash_map::set::LinkedHashSet, then? Or a separate crate? If the former, should there be a top-level re-export?

[Gankra]

I don't have any strong feelings on the matter.

Found myself looking for this. Trying to do cycle detection and report on the observed cycle.

[apasel422]

@nugend For the time being, you can use LinkedHashMap<SomeKey, ()>.

Ah, good idea!

I just published linked_hash_set, based on this project for anyone looking for LinkedHashSet.

Maintainers: If linked-hash-map ever spins up again feel free to grab the set code as you please. I think it makes sense to have along side the actual map implementation. If that ever happens lets me know so I can act accordingly.
