Bascially, this is because of limitations of cargo. It has no support for looking up dependencies in multiple places, only *one* source of dependencies is configurable. By default, dependencies are downloaded from crates.io. We override the "crates.io" source with the directory where Rust crates are packaged for Fedora. Using vendored dependencies works similarly - there, the "crates.io" source is overridden with the directory that contains vendored sources. But there is *no way* to specify *look here, and if it's not there, look elsewhere". If dependencies are not present in the one configured source, cargo just fails. So using packaged Rust crates for development is difficult - since you can't configure cargo to "use dependencies from "/usr/share/cargo/registry" and fall back to downloading from crates.io for things that aren't available". (Side note: The train for using a different suffix than "-devel" has left the station a decade ago. Changing this now is impractical, so the naming bikeshedding is not helping.)
