Documentation mismatch for scopeguard::guard_on_unwind

[wyf18]

Hello! 🐙
While scanning crates.io. we noticed a document-code mismatch issue in this crate, we think the doc examples are generally meant to illustrate why someone would want to use the item.

Location

documentation for scopeguard::guard_on_unwind
(https://docs.rs/scopeguard/1.1.0/scopeguard/fn.guard_on_unwind.html)

Summary

The example of the document does not mention the guard_on_unwind function, it is not clear how to use it.

Thank you for checking out this issue! 👍🤗

If there's any reason you don't think this is a mismatch issue, please let me know, we're doing an empirical study of documentation in the Rust ecosystem. Your answers will help us and better promote the development of the Rust ecosystem.

The example shows how to emulate guard_on_unwind in a no-std environment, so it isn't a documentation mismatch.
