Folks often post links to Rust Playground, e.g.:
But you have to click through to see the code they're talking about. Discourse has a feature called "Onebox" that can inline a rich summary for links. For instance there's a Onebox implemented for Gists:
https://gist.github.com/rust-play/8d4e99b8a7009d1bfc5a9c8744d21155
It looks like the Onebox repo is at https://github.com/discourse/onebox. Would folks here be interested in having a Onebox that would expand Rust Playground links the same way the gist link above is expanded?
