Overall

Stabilizes nonzero_min_max to allow the "infallible" construction of ordinary minimum and maximum NonZero* instances.

The feature is fairly straightforward and already matured for some time in stable toolchains.

let _ = NonZeroU8::MIN;
let _ = NonZeroI32::MAX;

History

  • On 2022-01-25, implementation was created.

Fixes #89065

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

  • Stabilizing library features
  • Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
  • Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
  • Changing public documentation in ways that create new stability guarantees
  • Changing observable runtime behavior of library APIs

In face of the discussion at https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/slow.20reviewing.20times arguing what would be a reasonable amount of waiting time and also because #75644 took ONE year to be reviewed, I will then try to roll the dices again. Feel free to revert any modification if desired.

Stabilize `nonzero_min_max`

## Overall

Stabilizes `nonzero_min_max` to allow the "infallible" construction of ordinary minimum and maximum `NonZero*` instances.

The feature is fairly straightforward and already matured for some time in stable toolchains.

```rust
let _ = NonZeroU8::MIN;
let _ = NonZeroI32::MAX;
```

## History

* On 2022-01-25, implementation was [created](rust-lang#93293).

## Considerations

* This report is fruit of the inanition observed after two unsuccessful attempts at getting feedback.
* Other constant variants discussed at rust-lang#89065 (comment) are orthogonal to this feature.

Fixes rust-lang#89065

Upstream changes:

Version 1.70.0 (2023-06-01)
==========================

Language
--------
- [Relax ordering rules for `asm!` operands]
  (rust-lang/rust#105798)
- [Properly allow macro expanded `format_args` invocations to uses
  captures] (rust-lang/rust#106505)
- [Lint ambiguous glob re-exports]
  (rust-lang/rust#107880)
- [Perform const and unsafe checking for expressions in `let _ =
  expr` position.]
  (rust-lang/rust#102256)

Compiler
--------
- [Extend -Cdebuginfo with new options and named aliases]
  (rust-lang/rust#109808)
  This provides a smaller version of debuginfo for cases that only
  need line number information (`-Cdebuginfo=line-tables-only`),
  which may eventually become the default for `-Cdebuginfo=1`.
- [Make `unused_allocation` lint against `Box::new` too]
  (rust-lang/rust#104363)
- [Detect uninhabited types early in const eval]
  (rust-lang/rust#109435)
- [Switch to LLD as default linker for {arm,thumb}v4t-none-eabi]
  (rust-lang/rust#109721)
- [Add tier 3 target `loongarch64-unknown-linux-gnu`]
  (rust-lang/rust#96971)
- [Add tier 3 target for `i586-pc-nto-qnx700` (QNX Neutrino RTOS,
  version 7.0)] (rust-lang/rust#109173),
- [Insert alignment checks for pointer dereferences as debug assertions]
  (rust-lang/rust#98112)
  This catches undefined behavior at runtime, and may cause existing
  code to fail.

  (rust-lang/rust#99929)
- [Fix handling of trailing bare CR in str::lines]
  (rust-lang/rust#100311)
- [allow negative numeric literals in `concat!`]

- [don't splice from files into pipes in io::copy]
  (rust-lang/rust#108283)
- [Add a builtin unstable `FnPtr` trait that is implemented for
  all function pointers]
  (rust-lang/rust#108080)
  This extends `Debug`, `Pointer`, `Hash`, `PartialEq`, `Eq`,
  `PartialOrd`, and `Ord` implementations for function pointers
  with all ABIs.

Compatibility Notes
-------------------

- [Prevent stable `libtest` from supporting `-Zunstable-options`]
  (rust-lang/rust#109044)
- [Perform const and unsafe checking for expressions in `let _ =
  expr` position.]
  (rust-lang/rust#102256)
- [WebAssembly targets enable `sign-ext` and `mutable-globals`
  features in codegen]
  (rust-lang/rust#109807)
  This may cause incompatibility with older execution environments.
- [Insert alignment checks for pointer dereferences as debug assertions]
  (rust-lang/rust#98112)
  This catches undefined behavior at runtime, and may cause existing
  code to fail.
