Dependencies

  • Bump the MSRV to 1.63.0 (#1207, #1246, #1269, #1341, #1416, #1536); note that 1.60.0 may work for dependents when using --ignore-rust-version
  • Update to rand_core v0.9.0 (#1558)

Features

  • Support std feature without getrandom or rand_chacha (#1354)

API changes: rand_core traits

  • Add fn RngCore::read_adapter implementing std::io::Read (#1267)
  • Add trait CryptoBlockRng: BlockRngCore; make trait CryptoRng: RngCore (#1273)
  • Add traits TryRngCore, TryCryptoRng (#1424, #1499)
  • Rename fn SeedableRng::from_rng -> try_from_rng and add infallible variant fn from_rng (#1424)
  • Rename fn SeedableRng::from_entropy -> from_os_rng and add fallible variant fn try_from_os_rng (#1424)
  • Add bounds Clone and AsRef to associated type SeedableRng::Seed (#1491)

API changes: Rng trait and top-level fns

  • Rename fn rand::thread_rng() to rand::rng() and remove from the prelude (#1506)
  • Remove fn rand::random() from the prelude (#1506)

  • Re-introduce fn Rng::gen_iter as random_iter (#1305, #1500)
  • Rename fn Rng::gen to random to avoid conflict with the new gen keyword in Rust 2024 (#1438)
  • Rename fns Rng::gen_range to random_range, gen_bool to random_bool, gen_ratio to random_ratio (#1505)
  • Annotate panicking methods with #[track_caller] (#1442, #1447)

API changes: RNGs

  • Fix <SmallRng as SeedableRng>::Seed size to 256 bits (#1455)
  • Remove first parameter (rng) of ReseedingRng::new (#1533)

API changes: Sequences

  • Split trait SliceRandom into IndexedRandom, IndexedMutRandom, SliceRandom (#1382)

⚠️ Semver Violation Detected ⚠️

This PR introduces breaking changes that violate semantic versioning rules.

Violation type: unknown
Current version: 0.6.0-pre

Required Action

You need to either:

  1. Revert the breaking changes to maintain backward compatibility, OR
  2. Take all of the following steps:
    • Update the version in Cargo.toml to a new version, depending on the type of semver violation
    • Document the breaking changes in BREAKING_CHANGES.md with details about what changed and how users should adapt

Note

Because we are still at version 0.X.Y, major semver violations require only a minor version bump (X), while minor semver violations require only a patch version bump (Y).

Breaking Changes Documentation

If you decide to keep the breaking changes, please make sure to:

  • Update BREAKING_CHANGES.md with a detailed explanation of the changes
  • Include information about how users should migrate their code
  • Specify which version introduces these changes

For more information on semantic versioning in Rust, please consult the Rust API Guidelines and Cargo's SemVer compatibility rules.
