[dependabot]

Bumps rand from 0.8.5 to 0.10.0.

Changelog

Sourced from rand's changelog.

[0.10.0] - 2026-02-08

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)

Note

Medium Risk
Dependency-only change, but rand is used for runtime salts/fingerprints and caching, so the upgrade could introduce subtle behavioral or API differences in randomness/backends across targets.

Overview
Updates the workspace dependency on rand from 0.8.5 to 0.10.0.

Refreshes Cargo.lock accordingly, pulling in new/updated transitive crates (notably chacha20, rand_core 0.10, getrandom 0.4, and WASI/WIT-related dependencies) and adjusting version pinning for shared deps like cpufeatures, hashbrown, and foldhash.

rand_chacha incompatible with rand 0.10

High Severity

rand was upgraded to 0.10.0 but rand_chacha stayed at 0.3.1, creating incompatible rand_core versions. Workspace code mixes rand traits with rand_chacha::ChaCha8Rng, so trait methods and seeding no longer line up and builds fail.
