When a user tries to use a method as if it returned a new value of the same type as its receiver, we will emit a type error. Try to detect this and provide extra explanation that the method modifies the receiver in-place. This has confused people in the wild, like in https://users.rust-lang.org/t/newbie-why-the-commented-line-stops-the-snippet-from-compiling/47322
Change `UnsafetyViolationKind::General` to `UnsafetyViolationKind::GeneralAndConstFn` in check_unsafety.rs Remove unsafe in min_const_fn_unsafe_bad.rs Bless min_const_fn Add the test case from issue 75340 Co-authored-by: lzutao <taolzu@gmail.com>

attempt to improve span_label docs I was still confused by the `span_label` docs, so I did some more digging. However, this needs careful checking as I have no idea if any of this is correct.
…r=RalfJung Add `as_uninit`-like methods to pointer types and unify documentation of `as_ref` methods This adds a convenient method to retrieve a `&(mut) [MaybeUninit<T>]` from slice pointers (`*const [T]`, `*mut [T]`, `NonNull<[T]>`). See also rust-lang/wg-allocators#66 (comment). ~I'll add a tracking issue as soon as it's reviewed and CI passed.~ Tracking Issue: rust-lang#75402 r? @RalfJung
…ascii, r=jyn514 Move to intra doc links for ascii.rs and panic.rs Helps with rust-lang#75080. @rustbot modify labels: T-doc, A-intra-doc-links, T-rustdoc I also updated the doc to fix the wording in `AsciiExt` since it is now deprecated. The two file are small changes so I bundled them together. Some links could not be changed to make them work, I believe those are known issues with primitive types.
Allowing raw ptr dereference in const fn Reflect on issue rust-lang#75340 Discussion in previous PR rust-lang#75425 ## Updates Change `UnsafetyViolationKind::General` to `UnsafetyViolationKind::GeneralAndConstFn` in check_unsafety.rs Remove `unsafe` in min_const_fn_unsafe_bad.rs Bless min_const_fn Add the test case from issue 75340 *** Sorry for the chaos. I messed up and ended up deleting the repo in the last PR. I have to create a new PR for the new repo. I will make a feature branch next time. I will edit the old PR once I receive the commends. @RalfJung Thank you all for your replies. They are helpful! r? @oli-obk
…ochenkov Add explanation for `&mut self` method call when expecting `-> Self` When a user tries to use a method as if it returned a new value of the same type as its receiver, we will emit a type error. Try to detect this and provide extra explanation that the method modifies the receiver in-place. This has confused people in the wild, like in https://users.rust-lang.org/t/newbie-why-the-commented-line-stops-the-snippet-from-compiling/47322
…kfire Clean up E0754 explanation r? @Dylan-DPC cc @pickfire
…jyn514 Use intra-doc links in `std::env`, `std::alloc` and `std::error` This is partial fixes for rust-lang#75080.
Mark x86_64-linux-kernel as * This should fix rust-lang#75581. This is my first contribution to the Rust organization. Please, feel free to tell me if I did anything wrong :)
