Rollup merge of #146136 - AudaciousAxiom:docs/missing-closing-code-block-fences, r=tgross35

docs(std): add missing closing code block fences in doc comments This PR adds a few closing code block fences which I believe are missing in some doc comments. It seems that rustdoc just autocloses code blocks at the end of doc comments and thus these were easily overlooked: I do not think these code blocks are special in any way. I found these when working on a Clippy lint that checks the last sentence of doc comments for terminal punctuation, and these were failing cases when testing against the std. Therefore I am not entirely sure these are all such cases, but still have high hopes that they are (or at least a well-defined subset of them).

Constify conversion traits (part 1) This is the first part of rust-lang/rust#144289 being split into smaller pieces. It adds/moves constness of several traits under the `const_convert` feature: * `From` * `Into` * `TryFrom` * `TryInto` * `FromStr` * `AsRef` * `AsMut` * `Borrow` * `BorrowMut` * `Deref` * `DerefMut` There are a few methods that are intrinsically tied to these traits which I've included in the feature. Particularly, those which are wrappers over `AsRef`: * `ByteStr::new` (unstable under `bstr` feature) * `OsStr::new` * `Path::new` Those which directly use `Into`: * `Result::into_ok` * `Result::into_err` And those which use `Deref` and `DerefMut`: * `Pin::as_ref` * `Pin::as_mut` * `Pin::as_deref_mut` * `Option::as_deref` * `Option::as_deref_mut` * `Result::as_deref` * `Result::as_deref_mut` (note: the `Option` and `Result` methods were suggested by ``@npmccallum`` initially as rust-lang/rust#146101) The parts which are missing from this PR are: * Anything that involves heap-allocated types * Making any method const than the ones listed above * Anything that could rely on the above, *or* could rely on system-specific code for `OsStr` or `Path` (note: this mostly makes these methods useless since `str` doesn't implement `AsRef` yet, but it's better to track the method for now and add impls later, IMHO) r? ``@tgross35`` (who mostly already reviewed this)

Clarify that align_offset overaligns

2025-08-28T18:07:38+00:00

The current documentation is not clear whether adding `a` to a pointer overaligns (align up) or underaligns (align down). It should say this explicitly.
