Build docs.rs with all features

[jeffa5]

The docs mention that an implementation for uuid is provided behind a feature flag. It would be more discoverable if this was reflected as a documented type, and so searchable.

Do you mean adding something like this to Cargo.toml

[package.metadata.docs.rs]
all-features = true

Or is there more that would need to be done?

[jeffa5]

I think that should do it
