Matthias Krüger 1df3a35bca Rollup merge of #136910 - okaneco:sig_ones, r=thomcc ... Implement feature `isolate_most_least_significant_one` for integer types Accepted ACP - https://github.com/rust-lang/libs-team/issues/467 Tracking issue - #136909 Implement ACP for functions that isolate the most significant set bit and least significant set bit on unsigned, signed, and `NonZero` integers. Add function `isolate_most_significant_one` Add function `isolate_least_significant_one` --- This PR adds the following impls ```rust impl {u8, u16, u32, u64, u128, usize} { const fn isolate_most_significant_one(self) -> Self; const fn isolate_least_significant_one(self) -> Self; } impl {i8, i16, i32, i64, i128, isize} { const fn isolate_most_significant_one(self) -> Self; const fn isolate_least_significant_one(self) -> Self; } impl NonZeroT { const fn isolate_most_significant_one(self) -> Self; const fn isolate_least_significant_one(self) -> Self; } ``` Example behavior ```rust assert_eq!(u8::isolate_most_significant_one(0b01100100), 0b01000000); assert_eq!(u8::isolate_least_significant_one(0b01100100), 0b00000100); ```		2025-02-22 11:36:42 +01:00
