Many crates detail in their docs that their crate needs Rust version 1.xx or above.
It would be great to have a standard place to document this. Should we just specify it as a dependency?
One might even be able to have compiler warnings that you’ve said it works with version 1.26 but you’re using a feature only available from 1.28.
Nightlies could be specified as well:
The current ‘rust’ crate on crates.io points to a 404 so that’s game for reuse.
Is there a better way - should there be a specific manifest location for this? Should it be mandatory to specify when publishing to crates.io?
Is there already a way to specify the min rust version that a crate requires?
