there's a list of removed/renamed lints somewhere to adjust the error message when using a renamed lint. Please add it there
r=me on the impl changes, please start a compiler FCP for this

Removing this old, useless lint that tells you if you are using Box. (Yes, really. Perhaps it made more sense in pre-1.0 days.) @rfcbot fcp merge |
How do I start an FCP? Or does it have to be started by a compiler team member? I'm only a contributor. |

Does anyone know how to trigger an FCP? |
rfcbot was having some trouble, which has been fixed-for-now, and it sounds like you should be able to just retry. |

☔ The latest upstream changes (presumably #120924) made this pull request unmergeable. Please resolve the merge conflicts. |
As the comment says, this lint "is mostly historical, and not particularly useful". It's not worth keeping it around.

Rust plugin support has been deprecated for four years and was removed in 1.75.0.](rust-lang/cargo#13902) <a id="1.81.0-Compatibility-Notes"></a> ## 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.](rust-lang/rust#126128) <a id="1.81.0-Internal-Changes"></a> ## 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.](rust-lang/rust#125209) </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.

Stabilized APIs --------------- - [`core::error`] (https://doc.rust-lang.org/stable/core/error/index.html) - [`hint::assert_unchecked`] (https://doc.rust-lang.org/stable/core/hint/fn.assert_unchecked.html) - [`fs::exists`] (https://doc.rust-lang.org/stable/std/fs/fn.exists.html) - [`AtomicBool::fetch_not`] (https://doc.rust-lang.org/stable/core/sync/atomic/struct.AtomicBool.html#method.fetch_not) - [`Duration::abs_diff`] (https://doc.rust-lang.org/stable/core/time/struct.Duration.html#method.abs_diff) - [`IoSlice::advance`] (https://doc.rust-lang.org/stable/std/io/struct.IoSlice.html#method.advance) - [`IoSlice::advance_slices`] (https://doc.rust-lang.org/stable/std/io/struct.IoSlice.html#method.advance_slices) - [`IoSliceMut::advance`] (https://doc.rust-lang.org/stable/std/io/struct.IoSliceMut.html#method.advance) - [`IoSliceMut::advance_slices`] (https://doc.rust-lang.org/stable/std/io/struct.IoSliceMut.html#method.advance_slices) - [`PanicHookInfo`] (https://doc.rust-lang.org/stable/std/panic/struct.PanicHookInfo.html) - [`PanicInfo::message`] (https://doc.rust-lang.org/stable/core/panic/struct.PanicInfo.html#method.message) - [`PanicMessage`] (https://doc.rust-lang.org/stable/core/panic/struct.PanicMessage.html) These APIs are now stable in const contexts: - [`char::from_u32_unchecked`] (https://doc.rust-lang.org/stable/core/char/fn.from_u32_unchecked.html) (function) - [`char::from_u32_unchecked`] (https://doc.rust-lang.org/stable/core/primitive.char.html#method.from_u32_unchecked) (method) - [`CStr::count_bytes`] (https://doc.rust-lang.org/stable/core/ffi/c_str/struct.CStr.html#method.count_bytes) - [`CStr::from_ptr`] (https://doc.rust-lang.org/stable/core/ffi/c_str/struct.CStr.html#method.from_ptr) Cargo ----- - [Generated `.cargo_vcs_info.json` is always included, even when `--allow-dirty` is passed.] (rust-lang/cargo#13960) - [Disallow `package.license-file` and `package.readme` pointing to non-existent files during packaging.] (rust-lang/cargo#13921) - [Disallow passing `--release`/`--debug` flag along with the `--profile` flag.] (rust-lang/cargo#13971) - [Remove `lib.plugin` key support in `Cargo.toml`. Rust plugin support has been deprecated for four years and was removed in 1.75.0.] (rust-lang/cargo#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.] (rust-lang/rust#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.] (rust-lang/rust#125209)
As the comment says, this lint "is mostly historical, and not particularly useful". It's not worth keeping it around.
