Hi @harryheng 👋

Without more context it looks like you're trying to depend on uuid, but hadn't specified it in your Cargo.toml? If you're new to Rust, you can see the docs on specifying dependencies. For this library, if you add the following to your Cargo.toml you should be set to use uuid:

[dependencies]
uuid = { version = "1", features = ["v4"] }
