Add another column to the homepage for "Most Recently Downloaded"

[carols10cents]

Instructions for fixing this, can be done in 2 separate PRs but they will need to be done in order :)

PR 1: backend

• In the summary function that returns JSON for the /api/v1/summary route, add a query similar to these queries that selects 10 crates sorted by recent downloads descending nulls last, which is defined by this query that's part of the index function (I'm fine with copy-pasting that code, if you feel ambitious and want to refactor to remove the duplication, feel free to give that a try!)
• Add a field for those crates to the returned data struct definition and the returned struct instance in the same manner as the other fields that return crates
• Add a test that 2 or 3 crates are returned in the expected order for this field, the CrateBuilder provides a way to set a crate's recent downloads for testing. The summary route isn't tested very much right now; a bonus would be adding more tests for the other parts of summary as well!

PR #2: Frontend

• Once /api/v1/summary returns recent downloads, add a section like these to display recent downloads. Please think of a good header for this, "Most Recently Downloaded" sounds like this is what crates people have downloaded in the last minute? "Most Downloaded in the Last 90 Days" is accurate but long. "Most Recent Downloads"? "Most Downloads Recently"?
• Check how it looks and at different browser widths; I think the CSS should Just Work but there's a chance it might need some tweaks :)

I would like to work on this issue but https://crates.io/api/v1/summary api does not return 'Most recently downloaded' information.

Yep, changing the API for the /api/v1/summary route to return this information is part of the issue actually. I got confused and thought #935 was about that, but it's not. Sorry for the misleading tags!

I have created a PR for the backend changes requested here.

I added some tests. However, oddly, when I run cargo test locally, it only runs the tests defined within the modules themselves. I'm trying to figure out how to run all the tests.

Hi @erewok!! Glad to have you here!! The behavior you're seeing with cargo test is definitely not expected... how can you tell it's only running the tests in src/krates/mod.rs? Could you gist the whole output you see from cargo test?

Hi @carols10cents. Thanks for the warm welcome! I am impressed with how well-run this project is.

At any rate, this morning I cloned the repo anew, built, and ran the tests and the problem seems to have disappeared. I'm not sure why it was ever there in the first place but it must have been user error. Thanks. I'm going to work on fixing the tests I wrote for the api/v1/summary endpoint.

The backend for this is now done, thank you @erewok !!!!

[sabinbajracharya]

@carols10cents As the backend is done, may I work on the frontend part?

[carols10cents]

@sabinbajracharya absolutely!
