The question says it all.
I am trying to figure out an easy way, if it exists, to look at a particular RFC or a PR and figure out which version of Rust it was stabilized in.
I do not want to parse the releases/tags section for information. It could get difficult if it is an older release.
I know if it is a function or API, the docs usually have a tag indicating when it was stable, like #[stable(feature = "rust1", since = "1.0.0")]
But what if it is a language feature/improvement like for example De-structuring assignments (RFC#2909).
This one was stabilized in 1.59.0 but I'd like a straightforward method of figuring it out.
