This is the relevant command from the docs.rs build:

In particular, --all-features is an issue with the mutually-conflicting tls and native-tls features. This post says:

Cargo doesn’t support mutually-exclusive features. Cargo will actively try to merge all features. In principle, all features are supposed to be additive.

The right solution would be to redesign the crate to allow all features at once (e.g. by namespacing the structs in separate modules, or making them generic).

reqwest has a similar situation with native-tls and rustls-tls features, and doesn't generate a compile-time error if you enable both. I'd recommend doing the same in ureq to get the docs to build.
