Rust plugin support has been deprecated for four years and was removed in 1.75.0.](https://redirect.github.com/rust-lang/cargo/pull/13902/) ## Compatibility Notes - Usage of the `wasm32-wasi` target will now issue a compiler warning and request users switch to the `wasm32-wasip1` target instead. Both targets are the same, `wasm32-wasi` is only being renamed, and this [change to the WASI target](https://blog.rust-lang.org/2024/04/09/updates-to-rusts-wasi-targets.html) is being done to enable removing `wasm32-wasi` in January 2025. - 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()`. - The new sort implementations may panic if a type's implementation of [`Ord`](https://doc.rust-lang.org/std/cmp/trait.Ord.html) (or the given comparison function) does not implement a [total order](https://en.wikipedia.org/wiki/Total_order) as the trait requires. `Ord`'s supertraits (`PartialOrd`, `Eq`, and `PartialEq`) must also be consistent. The previous implementations would not "notice" any problem, but the new implementations have a good chance of detecting inconsistencies, throwing a panic rather than returning knowingly unsorted data. - [In very rare cases, a change in the internal evaluation order of the trait solver may result in new fatal overflow errors.](https://redirect.github.com/rust-lang/rust/pull/126128) ## Internal Changes These changes do not affect any public interfaces of Rust, but they represent significant improvements to the performance or internals of rustc and related tools. - [Add a Rust-for Linux `auto` CI job to check kernel builds.](https://redirect.github.com/rust-lang/rust/pull/125209/) ### [`v1.80.1`](https://redirect.github.com/rust-lang/rust/blob/HEAD/RELEASES.md#Version-1801-2024-08-08) [Compare Source](https://redirect.github.com/rust-lang/rust/compare/1.80.0...1.80.1) \=========================== -

We're currently pinned to rust v1.64 due to nixos https://github.com/oxidecomputer/offline-keystore-os/issues/16. This should be held back until we have line-of-sight to getting that upgraded.

flihp commented 2 months ago

We're manually updating the pinned rust version in lock-step w/ OKOS updates.
