2023-03-23Rollup merge of #106964 - ↵Matthias Krüger-2/+10
workingjubilee:crouching-ioerror-hidden-documentation, r=ChrisDenton Clarify `Error::last_os_error` can be weird Fundamentally, querying the OS for error codes is a process that is deeply subject to the whims of chance and fortune. We can account for OS, but not for every combination of platform APIs. A compiled binary may not recognize new errors introduced years later. We should clarify a few especially odd situations, and what they mean: We can effectively promise nothing... if you ask for Rust to decode errors where none have occurred. This allows removing mention of ErrorKind::Uncategorized. That error variant is hidden deliberately, so we should not explicitly mention it. This fixes #106937. Since you had an opinion also: Does this solution seem acceptable? r? ``@ChrisDenton``

2022-08-28Rollup merge of #100296 - BlackHoleFox:os-error-aliases, r=thomccMatthias Krüger-0/+2
Add standard C error function aliases to last_os_error This aids the discoverability of `io::Error::last_os_error()` by linking to commonly used error number functions from C/C++. I've seen a few people not realize this exists, so hopefully this helps draw attention to the API to encourage using it over integer error codes.

2022-03-10Use implicit capture syntax in format_argsT-O-R-U-S-7/+7
This updates the standard library's documentation to use the new syntax. The documentation is worthwhile to update as it should be more idiomatic (particularly for features like this, which are nice for users to get acquainted with). The general codebase is likely more hassle than benefit to update: it'll hurt git blame, and generally updates can be done by folks updating the code if (and when) that makes things more readable with the new format. A few places in the compiler and library code are updated (mostly just due to already having been done when this commit was first authored).

r=joshtriplett Add #[must_use] to from_value conversions I added two methods to the list myself. Clippy did not flag them because they take `mut` args, but neither modifies their argument. ```rust core::str const unsafe fn from_utf8_unchecked_mut(v: &mut [u8]) -> &mut str; std::ffi::CString unsafe fn from_raw(ptr: *mut c_char) -> CString; ``` I put a custom note on `from_raw`: ```rust #[must_use = "call `drop(from_raw(ptr))` if you intend to drop the `CString`"] pub unsafe fn from_raw(ptr: *mut c_char) -> CString { ``` Parent issue: #89692 r? ``@joshtriplett``
