Stabilize new inclusive range type and iterator type Part 1 of stabilizing the new range types for rust-lang/rust#125687 stabilizes `core::range::RangeInclusive` and `core::range::RangeInclusiveIter`. Newly stable API: ```rust // in core and std pub mod range; // in core::range pub struct RangeInclusive<Idx> { pub start: Idx, pub last: Idx, } impl<Idx: fmt::Debug> fmt::Debug for RangeInclusive<Idx> { /* ... */ } impl<Idx: PartialOrd<Idx>> RangeInclusive<Idx> { pub const fn contains<U>(&self, item: &U) -> bool where Idx: [const] PartialOrd<U>, U: ?Sized + [const] PartialOrd<Idx>; pub const fn is_empty(&self) -> bool where Idx: [const] PartialOrd; } impl<Idx: Step> RangeInclusive<Idx> { pub fn iter(&self) -> RangeInclusiveIter<Idx>; } impl<T> const RangeBounds<T> for RangeInclusive<T> { /* ... */ } impl<T> const RangeBounds<T> for RangeInclusive<&T> { /* ... */ } impl<T> const From<RangeInclusive<T>> for legacy::RangeInclusive<T> { /* ... */ } impl<T> const From<legacy::RangeInclusive<T>> for RangeInclusive<T> { /* ... */ } pub struct RangeInclusiveIter<A>(/* ... */); impl<A: Step> RangeInclusiveIter<A> { pub fn remainder(self) -> Option<RangeInclusive<A>>; } impl<A: Step> Iterator for RangeInclusiveIter<A> { type Item = A; /* ... */ } impl<A: Step> DoubleEndedIterator for RangeInclusiveIter<A> { /* ... */ } impl<A: Step> FusedIterator for RangeInclusiveIter<A> { } impl<A: Step> IntoIterator for RangeInclusive<A> { type Item = A; type IntoIter = RangeInclusiveIter<A>; /* ... */ } impl ExactSizeIterator for RangeInclusiveIter<u8> { } impl ExactSizeIterator for RangeInclusiveIter<i8> { } unsafe impl<T> const SliceIndex<[T]> for range::RangeInclusive<usize> { type Output = [T]; /* ... */ } unsafe impl const SliceIndex<str> for range::RangeInclusive<usize> { type Output = str; /* ... */ } ``` I've removed the re-exports temporarily because from what I can tell, there's no way to make re-exports of stable items unstable. They will be added back and stabilized in a separate PR. |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
