This is the actual first item: log out the file tree. We can bake in the auth here, and break it out later.

Libraries we'll need:

XML parser
HTTP
Logging

Sketch | Iteration

Pass (copy of?) response vector into function as queue.
While queue is not empty:
- take first item from queue.
  - if it's a collection, get its children and append them to queue
  - if not, publicise it!

Handling the Option

In the loop, we need to advance the loop counter every time, the question is whether we do anything else. If we encounter a None, we should be able to ignore it & move on, but I'm not sure how to implement that.

Fixing incompatible match arms

Theyre just that: incompatible. An assignment statement returns the unit type (). A hash map insertion returns Option(V). So the latter needs to be inside a block that returns the unit type. The block can go on one line.

Great blog post on matching structs.

Great [blog post](https://blog.rust-lang.org/2015/04/17/Enums-match-mutation-and-moves.html) on matching structs.

You cant mutably borrow something after youve immutably borrowed it. Try mut Vec declaration again.

Maybe try taking out the Options, just to simplify the code. That should eliminate the immutable borrowings in match arms

Also do I have to call functions from traverse to handle immutable borrowings? and leave traverse purely mutable?

I've misunderstood ETags. The ETag of the first folder (test_public) is the same as that of its last item (2021_test_public), so the latter is not visited.

Logs of a recent run are in the scratchpad folder.

ETag is more like a timestamp.

Use href or clone of it.
