v0.10.0

Changes

• The dependency on rand_chacha has been replaced with a dependency on chacha20. This changes the implementation behind StdRng, but the output remains the same. There may be some API breakage when using the ChaCha-types directly as these are now the ones in chacha20 instead of rand_chacha (#​1642).
• Rename fns IndexedRandom::choose_multiple -> sample, choose_multiple_array -> sample_array, choose_multiple_weighted -> sample_weighted, struct SliceChooseIter -> IndexedSamples and fns IteratorRandom::choose_multiple -> sample, choose_multiple_fill -> sample_fill (#​1632)
• Use Edition 2024 and MSRV 1.85 (#​1653)
• Let Fill be implemented for element types, not sliceable types (#​1652)
• Fix OsError::raw_os_error on UEFI targets by returning Option<usize> (#​1665)
• Replace fn TryRngCore::read_adapter(..) -> RngReadAdapter with simpler struct RngReader (#​1669)
• Remove fns SeedableRng::from_os_rng, try_from_os_rng (#​1674)
• Remove Clone support for StdRng, ReseedingRng (#​1677)
• Use postcard instead of bincode to test the serde feature (#​1693)
• Avoid excessive allocation in IteratorRandom::sample when amount is much larger than iterator size (#​1695)
• Rename os_rng -> sys_rng, OsRng -> SysRng, OsError -> SysError (#​1697)
