…ls/alloc.rs` nicer - Use `.addr()` instead of `as`-cast - Use `add` instead of `offset` and remove some `as isize` casts by doing that - Remove some casts
…rminal The UNIX and WASI implementations use `isatty`. The Windows implementation uses the same logic the `atty` crate uses, including the hack needed to detect msys terminals. Implement this trait for `File` and for `Stdin`/`Stdout`/`Stderr` and their locked counterparts on all platforms. On UNIX and WASI, implement it for `BorrowedFd`/`OwnedFd`. On Windows, implement it for `BorrowedHandle`/`OwnedHandle`. Based on rust-lang#91121 Co-authored-by: Matt Wilkinson <mattwilki17@gmail.com>
If a process has no console, it'll have NULL in place of a console handle, so return early with `false` in that case without making any OS calls.
Rather than referencing a slice's pointer and then creating a new slice with a longer length, offset from the base structure pointer instead. This makes some choices of Rust semantics happier.
First try to use the system preferred RNG but if that fails (e.g. due to a broken system configuration) then fallback to manually opening an algorithm handle.
`fn is_zero` has been renamed to `fn count_is_zero` in 1b1bf24. This patch updates the documentation accordingly.
… r=thomcc Add `IsTerminal` trait to determine if a descriptor or handle is a terminal The UNIX implementation uses `isatty`. The Windows implementation uses the same logic the `atty` crate uses, including the hack needed to detect msys terminals. Implement this trait for `Stdin`/`Stdout`/`Stderr`/`File` on all platforms.

Refactor some `std` code that works with pointer offstes This PR replaces `pointer::offset` in standard library with `pointer::add` and `pointer::sub`, [re]moving some casts and using `.addr()` while we are at it. This is a more complicated refactor than all other sibling PRs, so take a closer look when reviewing, please 😃 (though I've checked this multiple times and it looks fine). r? ``@scottmcm`` _split off from rust-lang#100746, continuation of #100822_

…thomcc Remove `RtlGenRandom` (take two) First try to use the system preferred RNG but if that fails (e.g. due to a broken system configuration) then fallback to manually opening an algorithm handle.
…r=GuillaumeGomez rustdoc: CSS prevent sidebar width change jank This commit makes the `width` and `min-width` of the sidebar the same. They originally were when cad0fce added the `min-width` rule, but 6a5f8b1 changed the `width` without changing the `min-width`, causing it to sometimes oscilate between 200 and 250 pixels depending on the main content. # Before [Screencast from 09-22-2022 10:25:29 AM.webm](https://user-images.githubusercontent.com/1593513/191813469-ea00f30f-6f49-40fc-9a26-e1dfd5068d2b.webm) # After [Screencast from 09-22-2022 10:32:20 AM.webm](https://user-images.githubusercontent.com/1593513/191813642-ae0902da-5262-403a-bbdf-995334201acb.webm)
…=fee1-dead Add const_closure, Constify Try trait Adds a struct for creating const `FnMut` closures (for now just copy pasted form my [const_closure](https://crates.io/crates/const_closure) crate). I'm not sure if this way is how it should be done. The `ConstFnClosure` and `ConstFnOnceClosure` structs can probably also be entirely removed. This is then used to constify the try trait. Not sure if i should add const_closure in its own pr and maybe make it public behind a perma-unstable feature gate. cc `@fee1-dead` `@rust-lang/wg-const-eval`
…n514 Update doc after renaming `fn is_zero` `fn is_zero` has been renamed to `fn count_is_zero` in 1b1bf24. This patch updates the documentation accordingly.
Document some missing command-line arguments The rustc command-line arguments docs should document all of the stable arguments for rustc. Two were missing, `--force-warn` which was somewhat documented in the lint-levels chapter, but should also include a mention in the arguments list. `--diagnostic-width` was stabilized in rust-lang#95635, but the docs weren't updated.
