Grind Time Backend

This is a small Rust API which acts as the backend for our Grind Time App.

Features

• Authentication
• Leader board table
• Account table

Authentication

• Each new device will use a symmetric key to register a new account with the backend
• The device will generate a name and a secret key that the database will share
• After the account is created, the device will forget the original symmetric key
  • The device will then use the key it generated for authentication

Leader board table

• A table of the top ten times for each location will be stored
• The table will contain a username, user id, minute duration, and location id
  • username + id avoids joins — which I am terrified of
  • The location id will be used to reference the name and location of the building

Account table

• Will store username and id of each user that registers
• Used for authenticating client requests
• In the future will likely store other user details
