In this video, we explored some interesting crates that can be useful when building web projects or integration software with the Rust programming language:

- Dotenv (to load environment variables from .env files): https://crates.io/crates/dotenv
- Reqwest (an async HTTP client): https://crates.io/crates/reqwest
- Url (to parse and build URLs programmatically): https://crates.io/crates/url
- Serde & Serde JSON (to parse JSON data): https://serde.rs/


The code is available here: https://github.com/lmammino/rust-lastfm
