Use `NonNull::without_provenance` within the standard library

2025-01-10T22:23:10+00:00

This API removes the need for several `unsafe` blocks, and leads to clearer code.

Stabilize `std::io::ErrorKind::QuotaExceeded`

2024-10-05T18:42:13+00:00

Also drop "Filesystem" from its name

Mark some more types as having insignificant dtor

The previous commit updated `rustfmt.toml` appropriately. This commit is the outcome of running `x fmt --all` with the new formatting options.

Add `size_of`, `size_of_val`, `align_of`, and `align_of_val` to the prelude

2024-05-13T13:11:28+00:00

Many, many projects use `size_of` to get the size of a type. However, it's also often equally easy to hardcode a size (e.g. `8` instead of `size_of::()`). Minimizing friction in the use of `size_of` helps ensure that people use it and make code more self-documenting. The name `size_of` is unambiguous: the name alone, without any prefix or path, is self-explanatory and unmistakeable for any other functionality. Adding it to the prelude cannot produce any name conflicts, as any local definition will silently shadow the one from the prelude. Thus, we don't need to wait for a new edition prelude to add it. Add `size_of_val`, `align_of`, and `align_of_val` as well, with similar justification: widely useful, self-explanatory, unmistakeable for anything else, won't produce conflicts.

Use generic `NonZero` everywhere in `std`.
