In Rust for Linux we are using these to make `alloc` a bit more modular. A `run-make-fulldeps` test is added for each of them, so that enabling each of them independently is kept in a compilable state. Signed-off-by: Miguel Ojeda <ojeda@kernel.org>
The prose talked about doing this, so might as well add a simple code example of it too.
State up-front and center what shape the returned extension will have, without making the user read through the description and examples. Rationale: Various frameworks and libraries for different platforms have their different conventions as to whether an "extension" is ".ext" or just "ext" and anyone that's had to deal with this ambiguity in the past is always double- or triple-checking to make sure the function call returns an extension that matches the expected semantics. Offer the answer to this important question right off the bat instead of making them dig to find it.
It's now much more like the `-Zhir-stats` output. - Each line is preceded with `meta-stats`, which makes the provenance clearer and allows filtering of the output. - Sections are now sorted in reverse order of size. - Column headings avoid the need to repeat the word "bytes" on every line. - Long numbers now have `_` separators for easier reading. - Consistent use of '-' within section labels, rather than a mix of '-', '_', and ' '. The code itself is shorter and easier to read thanks to: - the `stat` macro, which encapsulates each section's encoding, avoids some boilerplate, and removes the need for some low-value comments; - the `stats` vector, which replaces dozens of local variables.
`alloc`: add unstable cfg features `no_rc` and `no_sync` In Rust for Linux we are using these to make `alloc` a bit more modular. See rust-lang#86048 and rust-lang#84266 for similar requests. Of course, the particular names are not important.
…ark-Simulacrum Add another example for `uN::carrying_mul` The prose talks about doing this, so might as well add a simple code example of it too.
…race, r=tmandry Adding ignore fuchsia tests for Backtrace, ErrorKind cases Tests where Backtrace parses are required (invalid since Fuchsia backtraces are not symbolized), and test where ErrorKind is not properly translated from a Fuchsia-style to Unix-style error code cc. ``@djkoloski`` r? ``@tmandry``
…bjorn3 Improve `-Zmeta-stats` some more A follow-up to rust-lang#97384. r? ``@bjorn3``
…, r=oli-obk fix ConstProp handling of written_only_inside_own_block_locals Fixes a regression introduced by rust-lang#100239, which adds an early return and thus skips some code in `visit_terminator` that must be run for soundness. Fixes rust-lang#101973
Clarify Path::extension() semantics in docs abstract State up-front and center what shape the returned extension will have, without making the user read through the description and examples. This is a doc-only change. There are no changes to the API contract and the clarification is in line with what was already stated/promised in the existing doc text - just clarified, summarized, and served bright and early. Rationale: Various frameworks and libraries for different platforms have their different conventions as to whether an "extension" is ".ext" or just "ext" and anyone that's had to deal with this ambiguity in the past is always double- or triple-checking to make sure the function call returns an extension that matches the expected semantics.

…dth, r=GuillaumeGomez rustdoc: remove unnecessary `max-width` on headers This code was added in 003b2bc to prevent these headers from overlapping `.out-of-band` side items. That stopped being a problem when 3f92ff3 switched rustdoc over to using `float`, rather than `position: absolute`, to implement this.
