[nik-rev]

Feature gate: #![feature(new_range_end_bound)]

This is a tracking issue for rust-lang/libs-team#653

Public API

Before

// core::range
struct RangeInclusive<T>;
struct Range<T>;

// core::ops
trait RangeBounds<T: ?Sized> {
    fn start_bound(&self) -> Bound<&T>;

    fn end_bound(&self) -> Bound<&T>;
}

After

// core::range
struct RangeInclusive<Start, End = Start>;
struct Range<Start, End = Start>;

// core::ops
trait RangeBounds<Start: ?Sized, End: ?Sized = Start> {
    fn start_bound(&self) -> Bound<&Start>;

    fn end_bound(&self) -> Bound<&End>;
}
