Bumps rand from 0.8.8 to 0.10.2.

Changelog

Sourced from rand's changelog.

[0.10.2] — 2026-07-02

Fixes

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

Changes

  • Document required output order of fn partial_shuffle and apply #[must_use] (#1769)
  • Avoid usage of unsafe in contexts where non-local memory corruption could invalidate contract (#1791)

#1769: rust-random/rand#1769 #1790: rust-random/rand#1790 #1791: rust-random/rand#1791

[0.10.1] — 2026-02-11

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)

#1761: rust-random/rand#1761 #1763: rust-random/rand#1763

[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)

The random-number dependency was upgraded to a version whose API renamed the functions this project still calls, so the build will fail until those call sites are updated. The dependency bump should not be merged on its own without that code change.

In `@Cargo.toml`:
- Line 18: Update the rand usage in crates/utils/src/lib.rs for rand 0.10:
replace the rand::Rng import with rand::RngExt, use rand::rng() instead of
rand::thread_rng(), and change each rng.gen() call to rng.random(). Preserve
existing fill calls through RngExt.
- Line 18: Update the rand usage in the utility code by replacing the rand::Rng
import with rand::RngExt, rand::thread_rng-style initialization with
rand::rng(), and rng.gen() calls with rng.random(). Also declare Rust 1.85 as
the workspace MSRV, or select a rand version compatible with the existing
supported Rust version.
