Release Notes

rust-random/rand (rand)

v0.10.3

Compare Source

Fixes

• Fix WeightedIndex panic when the sum of float weights is infinite; return Error::Overflow instead (#​1808)
• Fix spurious Error::NonFinite from Uniform::new_inclusive on large finite float ranges such as 0.0..=f64::MAX (#​1821)
• Fix possible panic due to sampling a deserialized Uniform<char> (#​1831)

Changes

• Report exact remaining lengths from WeightedIndex::weights() and reduce overhead when reading weights (#​1838)

v0.10.2

Compare Source

Fixes

• Fix possible memory safety violation due to deserialization of UniformChar from bad source (#​1790)

Changes

v0.10.1

Compare Source

This release includes a fix for a soundness bug; see #​1763.

Changes

• Document panic behavior of make_rng and add #[track_caller] (#​1761)
• Deprecate feature log (#​1763)

v0.10.0

Compare Source

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)
• Rename Rng -> RngExt as upstream rand_core has renamed RngCore -> Rng (#​1717)

Additions

• Add fns IndexedRandom::choose_iter, choose_weighted_iter (#​1632)
• Pub export Xoshiro128PlusPlus, Xoshiro256PlusPlus prngs (#​1649)
• Pub export ChaCha8Rng, ChaCha12Rng, ChaCha20Rng behind chacha feature (#​1659)
• Fn rand::make_rng() -> R where R: SeedableRng (#​1734)

Removals

• Removed ReseedingRng (#​1722)
• Removed unused feature "nightly" (#​1732)
• Removed feature small_rng (#​1732)
