We don't want to render default item docs but previously
`doctraititem` naively delegated to the trait definition in those
cases.
Updated tests to also check that this doesn't strip default item
docs from the trait definition.
collections: Add slice::binary_search_by_key
This method adds to the family of `_by_key` methods, and is the
counterpart of `slice::sort_by_key`. It was mentioned on #30423 but
was not implemented at that time.
Refs #30423
In `test/rustdoc/manual_impl.rs` there are now three structs:
* S1 implements and documents required method `a_method`.
* S2 implements and documents `a_method` as well as provided
method `b_method`.
* S3 implements `a_method` and `b_method`, but only documents
`b_method`.
For a struct, we want the rendered trait impls to include documentation
if and only if it appears on the trait implementation itself
(since users can just go to the trait definition for anything not
covered in the impl docs). This means we expect:
* S1, S2, and S3 to all include top-level trait impl docs.
* S1, S2, and S3 to exclude all trait definition docs.
* S1 to show impl docs for `a_method`.
* S2 to show impl docs for `a_method` and `b_method`.
* S3 to show impl docs for `b_method`.
These tests cover those cases.
Deduplicate libraries on hash instead of filename.
Removes the need for canonicalization to prevent #12459.
(Now with passing tests!)
Canonicalization breaks certain environments where the libraries are symlinks to files that don't end in .rlib (e.g. /remote/cas/$HASH).
This modifies our listing of tiered platforms a few ways:
* All lists are alphabetized based on target now
* Lots of targets are moved up to "Tier 2" as we're gating on all these builds
and official releases are provided (and installable via rustup).
* A few targets now list having a compiler + cargo now as well.
No more platforms have been moved up to Tier 1 at this time, however. The only
real candidate is ``x86_64-unknown-linux-musl`, but that's not *quite* to a tier
1 level of quality just yet so let's hold off for another release or so to iron
it out a bit.
Fix conflicting link identifiers
Caused "Errors for non-exhaustive match patterns now list up to 3 missing variants while also indicating the total number of missing variants if more than 3." to link to "libsyntax: Restrict where non-inline modules can appear (fixes#29765)"
Add rustbuild option to use Ninja for LLVM build
This change adds support for a `ninja` option in the `[llvm]` section of rustbuild's `config.toml`. When `true`, the option enables use of the Ninja build tool. Note that this change does not add support for Ninja to the old makefile based build system.

librustc_back: fix incorrect comment about RUST_TARGET_PATH
The path `/etc/rustc/` is not the default last entry in
RUST_TARGET_PATH. This was in RFC131 but was never implemented in rustc
so it was removed as part of #31117 and rust-lang/rfcs#1473.

Don't read past limit for in BufRead instance of Take
Similar to `Read::read`, `BufRead::fill_buf` impl of `Take` should not call `inner.fill_buf` if the limit is already reached.
don't report errors in constants at every use site
partially fixes#32842
r? @arielb1
cc @retep998
I chose this way of implementing it, because the alternative (checking if the error span is inside the constant's expressions's span) would get confusing when combined with expression generating macros.
A next step would be to re-enable the re-reporting of errors if the original erroneous constant is in another crate.
