Hey! It looks like you've submitted a new PR for the library teams! If this PR contains changes to any Examples of
|
| /// result | ||
| /// // the mutex guard gets dropped here, together with any other values | ||
| /// // created in the critical section. | ||
| /// }; | ||
| /// *res_mutex_clone.lock().unwrap() += result; |
There was a problem hiding this comment.
I think it's worth commenting that this res guard is a temporary, dropped at the end of this statement.

That is already mentioned in the 2nd example below which uses drop() instead of a block, but I added it here too.
