Because it's used within both `TypedArena` and `DroplessArena`. The commit also makes `<u8>` the default parameter.
Incorporate distance limit from `find_best_match_for_name` directly into Levenshtein distance computation. Use the string size difference as a lower bound on the distance and exit early when it exceeds the specified limit. After finding a candidate within a limit, lower the limit further to restrict the search space.
I found this message confusing when I encountered it. This commit makes it clearer that you have to import the unqualified type yourself.
It's simply a binary thing to allow different behaviour for `Copy` vs `!Copy` types. The new code makes this much clearer; I was scratching my head over the old code for some time.
Define c_char using cfg_if rather than repeating 40-line cfg Libstd has a 40-line cfg that defines the targets on which `c_char` is unsigned, and then repeats the same cfg with `not(…)` for the targets on which `c_char` is signed. This PR replaces it with a `cfg_if!` in which an `else` takes care of the signed case. I confirmed that `x.py doc library/std` inlines the type alias because c_char_definition is not a publicly accessible path: 
Mention std::iter::zip in Iterator::zip docs Closes rust-lang#91960 I'm not sure about the wording. I think it's alright, but happy to change.
…, r=the8472 Add test for stable hash uniqueness of adjacent field values This PR adds a simple test to check that stable hash will produce a different hash if the order of two values that have the same combined bit pattern changes. r? `@the8472`
Introduce a limit to Levenshtein distance computation Incorporate distance limit from `find_best_match_for_name` directly into Levenshtein distance computation. Use the string size difference as a lower bound on the distance and exit early when it exceeds the specified limit. After finding a candidate within a limit, lower the limit further to restrict the search space.
