The other methods from UnicodeStr are already stable inherent
methods on str, but these have not been included.

Is there a reason why these methods are not available on core? Is there anything inherently preventing them from being available there?

@SimonSapin

These methods are based on (potentially-large) Unicode tables. The std_unicode crate exists to contain these tables, but I think we might be able to move all of this into libcore? That’s out of scope for this PR though.

When we were talking about which methods from AsciiExt to copy to str, we purposefully excluded methods like is_ascii_alphabetic because we preferred the explicit version (cc @dtolnay). I guess we should be consistent here... 😕

I mean, the meaning of s.is_whitespace() is a lot clearer than s.is_ascii_hexdigit(), but still. Just wanted to bring this up, what do you think?

@SimonSapin

That’s a good point. @rust-lang/libs, any opinion?

@BurntSushi

I also personally like the explicit variant to the exclusion of the higher level methods. Basically for reasons already stated.

I would prefer not to have these methods.

I filed #49657 with regression-from-stable-to-beta tag to follow up. @LukasKalbertodt I'm not sure how you caught this but thanks! 🍻

@dtolnay In case that's not a rhetoric question: this PR was linked on TWiR. I only landed one big PR in this repo (the AsciiExt thing) and I thus take a closer look at everything that is vaguely related to my PR 😁

Tweak some stabilizations in libstd
ca79ba3 
This commit tweaks a few stable APIs in the `beta` branch before they hit
stable. The `str::is_whitespace` and `str::is_alphanumeric` functions were
deleted (added in rust-lang#49381, issue at rust-lang#49657). The `and_modify` APIs added
in rust-lang#44734 were altered to take a `FnOnce` closure rather than a `FnMut` closure.
