Building web APIs with Rust (advanced)

Learn to set up a Rust Rocket web API by adding dependencies, defining routes, mounting them, enabling json, and wiring a Postgres pool via Rocket db pools with env vars.

Design and build rustacean endpoints in a rocket-based api, using serde json for serialization and deserialization. Implement get, create, update, delete with proper http status codes and robust error handling.

Design and implement a users and roles system with a pivot table to enable granular access control in a Rust web API, including migrations, models, and associations.

Create a create user command in a cli module with username and password. Include role codes and load db url from env for async Postgres connection via Tokio and repositories.

Implement a login endpoint in a rocket-based app, accepting json credentials payload (username and password), querying the user repository and verifying the password with Argon2 to return success or unauthorized.

Refactor the login flow by extracting a reusable auth module that verifies user credentials with Argon2. Generate a 128-character alphanumeric session token and enable reuse across routes and CLI.

Define role codes as enums to enable granular access control in a Rust web API, with admin, editor, and viewer roles implemented via diesel traits and FromStr.

Celebrate completing the Rust web APIs course as you recap endpoints, JSON, commands, CLIs, and database interactions with Postgres and Redis, while mastering tests and safe deployment.
