`isize` is a rare integer type, replace it with a more common one.
The following suggestion is incorrect, as it doesn't account for the binding: ``` error[E0599]: no method named `poll` found for type parameter `F` in the current scope --> $DIR/pin-needed-to-poll-3.rs:19:28 | LL | impl<F> Future for FutureWrapper<F> | - method `poll` not found for this type parameter ... LL | let res = self.fut.poll(cx); | ^^^^ method not found in `F` | help: consider pinning the expression | LL ~ let res = let mut pinned = std::pin::pin!(self.fut); LL ~ pinned.as_mut().poll(cx); | ```
When we encounter a situation where we'd suggest `pin!()`, we now account for that expression exising as part of an assignment and provide an appropriate suggestion: ``` error[E0599]: no method named `poll` found for type parameter `F` in the current scope --> $DIR/pin-needed-to-poll-3.rs:19:28 | LL | impl<F> Future for FutureWrapper<F> | - method `poll` not found for this type parameter ... LL | let res = self.fut.poll(cx); | ^^^^ method not found in `F` | help: consider pinning the expression | LL ~ let mut pinned = std::pin::pin!(self.fut); LL ~ let res = pinned.as_mut().poll(cx); | ``` Fix rust-lang#125661.

It no longer needs to be public.
We can just set the payload immediately in the constructor, and the constructor does not need to be public.
In the other functions, we put the struct and impl blocks first, such that the return expression can be at the end of the body as usual.
…=Amanieu Split core's PanicInfo and std's PanicInfo `PanicInfo` is used in two ways: 1. As argument to the `#[panic_handler]` in `no_std` context. 2. As argument to the [panic hook](https://doc.rust-lang.org/stable/std/panic/fn.set_hook.html) in `std` context. In situation 1, the `PanicInfo` always has a *message* (of type `fmt::Arguments`), but never a *payload* (of type `&dyn Any`). In situation 2, the `PanicInfo` always has a *payload* (which is often a `String`), but not always a *message*. Having these as the same type is annoying. It means we can't add `.message()` to the first one without also finding a way to properly support it on the second one. (Which is what rust-lang#66745 is blocked on.) It also means that, because the implementation is in `core`, the implementation cannot make use of the `String` type (which doesn't exist in `core`): https://github.com/rust-lang/rust/blob/0692db1a9082380e027f354912229dfd6af37e78/library/core/src/panic/panic_info.rs#L171-L172 This also means that we cannot easily add a useful method like `PanicInfo::payload_as_str() -> Option<&str>` that works for both `&'static str` and `String` payloads. I don't see any good reasons for these to be the same type, other than historical reasons. --- This PR is makes 1 and 2 separate types. To try to avoid breaking existing code and reduce churn, the first one is still named `core::panic::PanicInfo`, and `std::panic::PanicInfo` is a new (deprecated) alias to `PanicHookInfo`. The crater run showed this as a viable option, since people write `core::` when defining a `#[panic_handler]` (because they're in `no_std`) and `std::` when writing a panic hook (since then they're definitely using `std`). On top of that, many definitions of a panic hook don't specify a type at all: they are written as a closure with an inferred argument type. (Based on some thoughts I was having here: rust-lang#115561 (comment)) --- For the release notes: > We have renamed `std::panic::PanicInfo` to `std::panic::PanicHookInfo`. The old name will continue to work as an alias, but will result in a deprecation warning starting in Rust 1.82.0. > > `core::panic::PanicInfo` will remain unchanged, however, as this is now a *different type*. > > The reason is that these types have different roles: `std::panic::PanicHookInfo` is the argument to the [panic hook](https://doc.rust-lang.org/stable/std/panic/fn.set_hook.html) in std context (where panics can have an arbitrary payload), while `core::panic::PanicInfo` is the argument to the [`#[panic_handler]`](https://doc.rust-lang.org/nomicon/panic-handler.html) in no_std context (where panics always carry a formatted *message*). Separating these types allows us to add more useful methods to these types, such as `std::panic::PanicHookInfo::payload_as_str()` and `core::panic::PanicInfo::message()`.
Remove usage of `isize` in example `isize` is a rare integer type, replace it with a more common one.
…v64gc-update, r=Kobzol CI: Update riscv64gc-linux job to Ubuntu 22.04, rename to riscv64gc-gnu Together with joshua.zivkovic@codethink.co.uk, we've been starting to explore improving the state of the `riscv64gc-unknown-linux-gnu` target. Additionally, I'm looking to add support for this platform in [Ferrocene](https://github.com/ferrocene/ferrocene) ([Related PR](ferrocene/ferrocene#618)).

It does so through bringing the `riscv64gc-unknown-linux-gnu` related test job in line with other related jobs, adopting many of the recent changes present in `src/ci/docker/host-x86_64/armhf-gnu` such as: * Using Ubuntu 22.04 * Installing a more narrowly scoped package set * Using `curl` instead of `debootstrap` to set up the root * No longer patching `busybox` * Removing the `cmake.sh` script related steps ## Justifying Renaming `riscv64gc-linux` to `riscv64gc-gnu` The `src/ci/docker/host-x86_64/disabled/riscv64gc-linux` job runs the tests for `risv64gc-unknown-linux-gnu`, it is based off `src/ci/docker/host-x86_64/armhf-gnu`. There are other jobs that follow a `$arch-gnu` naming scheme: * `src/ci/docker/host-x86_64/armhf-gnu` * `src/ci/docker/host-x86_64/x86_64-gnu` * `src/ci/docker/host-aarch64/aarch64-gnu` It follows that the name `src/ci/docker/host-x86_64/disabled/riscv64gc-linux` should be `src/ci/docker/host-x86_64/disabled/riscv64gc-gnu`, like the others. ## Testing > [!NOTE] > `riscv64gc-unknown-linux-gnu` is a [**Tier 2 with Host Tools** platform](https://doc.rust-lang.org/beta/rustc/platform-support.html), all tests may not necessarily pass!
