Error handling needs to be added so that encryption errors or bins not being found return a proper status code, and a new JSON object like so:

{
    "error": "bin not found"
}

With work already put into place to abstract the database into a trait, as well as the encryption client, we have the infrastructure to support real unit tests with mockall.

A front end needs to be created to interact with the backend. Unsure of approach, current thoughts are:

1. React: very much overkill, but it would be good to get experience with. Can use premade component libraries.
2. Tailwind + Handlebars: Not a fan, would have to style myself with tailwind's classes.
3. Bootstrap: fine, but so 2016

We can create a build.rs file that will compile the frontend and place it into a public dir or something to statically serve.
