the trait Deserialize is not implemented for `Uuid`

[andinus]

I'm not sure what caused this, I did not commit Cargo.lock so I'm unable to get back to earlier state. I'm getting these errors when building a project:

28   |     pub id: Uuid,

Hi @andinus :wave:

If you add the serde feature of uuid to your Cargo.toml that should get you back to good:

uuid = { version = "1.7", features = ["serde"] }

Chances are another dependency somewhere in your dependency tree also depended on uuid and was bringing in this feature already, but isn't anymore.

Thank you that fixed it. My bad, I didn't realize it could be this, I was fiddling with other things.

Also, thank you for uuid :)
