a1b24768a6 Clean up the prelude docs
This mostly brings them in line with existing linking convention, but
also has some minor re-wording.

The text at the top has been re-focused, by starting out with what the
prelude does, rather than starting from injecting std.

Also, it now mentions that other preludes exist.

662232c8f6 Rewrite match algorithm to avoid massive blowup in generated code for
large matches that fallback to Eq. When we encounter a case where the
test being performed does not inform the candidate at all, we just stop
testing the candidates at that point, rather than adding the candidate
to both outcomes. The former behavior was not WRONG, but it generated a
lot of code, whereas this new behavior degenerates to an if-else-if
tree.

Fixes #29740.

3ef3fd96cf Rollup merge of #29775 - arcnmx:raw-c_char, r=alexcrichton
It's a bit strange to expect users of `libstd` to require the use of an external crates.io crate to work with standard types. This commit encourages the use `os::raw::c_char` instead, although users are certainly free to use `libc::c_char` if they wish; the test still exists to ensure the two types are identical (though the reported bug only exists on platforms that are not officially tested).

Fixes #29774

f1f5c04c07 Auto merge of #29763 - nikomatsakis:mir-29227, r=nikomatsakis
The older algorithm was pretty inefficient for big matches. Fixes #29227. (On my computer, MIR construction on this test case goes from 9.9s to 0.025s.) Whereas before we had a loop like:

- for all outcomes of the test we are performing
    - for all candidates
        - check whether candidate is relevant to outcome

We now do:

- for all candidates
    - determine which outcomes the candidate is relevant to

Since the number of outcomes in this case is proportional to the number of candidates, the original algorithm turned out to be O(n^2), and the newer one is just O(n).

This PR also does some minor speedups by eagerly mirroring all patterns, so that we can just pass around `&Pattern<'tcx>`, which makes cloning cheaper. We could probably go a bit further in this direction.

4879078f2e Allow none Sized types in assert_eq!
format_args! doesn't support none Sized types so we should just pass it the references to left_val and right_val.

This fixes `assert_eq!([1, 2, 3][..], vec![1, 2, 3][..])` for example.

0471b3247d Reorganize match construction to be O(n) instead of O(n^2). Whereas
before we iterated over the test and each outcome thereof, and then
checked processed every candidate against this outcome, we now organize
the walk differently. Instead, we visit each candidate and say "Here is
the test being performed. Figure out the resulting candidates for each
possible outcome and add yourself into the appropriate places."

- Check privacy sanity in all blocks, not only function bodies
- Check all fields, not only named
- Check all impl items, not only methods
- Check default impls
- Move the sanity check in the beginning of privacy checking, so others could rely on it

Technically it's a [breaking-change], but I expect no breakage because, well, it's *sane* privacy visitor, if code is broken it must be insane by definition!

3519effc6e Auto merge of #29724 - alexcrichton:ip-endian, r=aturon
The comparison of IP addresses should happen not always in network endianness
but rather in the host endianness format, so be sure to convert to that before
comparing addresses.

There are still locations where the endianness will factor into visible
properties, such as the hash, but these are not important to be independent of
the endianness in play (as hash values are pretty undefined anyway.

This completely abdicates any responsibility to explain what Rust is, instead linking to the website.

My main motivation is that I am still not happy with it, and every time I try to fix it I just write a slightly longer sales pitch than what's on the website.

One thing this paragraph could do is direct people to more information about what is in the repo, or more technical information about the implementation.
