Bumps rand_distr from 0.4.3 to 0.6.0.

Release notes

Sourced from rand_distr's releases.

0.5.1

What's Changed

New Contributors

Full Changelog: rust-random/rand_distr@0.5.0...0.5.1

0.5.0

Dependencies and features

  • Bump the MSRV to 1.61.0 (#1207, #1246, #1269, #1341, #1416); note that 1.60.0 may work for dependents when using --ignore-rust-version
  • Update to rand v0.9.0 (#1558)
  • Rename feature serde1 to serde (#1477)

API changes

  • Make distributions comparable with PartialEq (#1218)
  • Dirichlet now uses const generics, which means that its size is required at compile time (#1292)
  • The Dirichlet::new_with_size constructor was removed (#1292)
  • Add WeightedIndexTree (#1372, #1444)
  • Add PertBuilder to allow specification of mean or mode (#1452)
  • Rename Zeta's parameter a to s (#1466)
  • Mark WeightError, PoissonError, BinomialError as #[non_exhaustive] (#1480)
  • Remove support for usage of isize as a WeightedAliasIndex weight (#1487)
  • Change parameter type of Zipf::new: n is now floating-point (#1518)

API changes: renames

  • Move Slice -> slice::Choose, EmptySlice -> slice::Empty (#1548)
  • Rename trait DistString -> SampleString (#1548)
  • Rename DistIter -> Iter, DistMap -> Map (#1548)
  • Move {Weight, WeightError, WeightedIndex} -> weighted::{Weight, Error, WeightedIndex} (#1548)
  • Move weighted_alias::{AliasableWeight, WeightedAliasIndex} -> weighted::{..} (#1548)
  • Move weighted_tree::WeightedTreeIndex -> weighted::WeightedTreeIndex (#1548)

Testing

Fixes

  • Fix Knuth's method so Poisson doesn't return -1.0 for small lambda (#1284)
  • Fix Poisson distribution instantiation so it return an error if lambda is infinite (#1291)
  • Fix Dirichlet sample for small alpha values to avoid NaN samples (#1209)
  • Fix infinite loop in Binomial distribution (#1325)
  • Fix Pert distribution where mode is close to (min + max) / 2 (#1452)
  • Fix panic in Binomial (#1484)
  • Limit the maximal acceptable lambda for Poisson to solve (#1312) (#1498)
  • Fix bug in Hypergeometric, this is a Value-breaking change (#1510)

Other changes

  • Remove unused fields from Gamma, NormalInverseGaussian and Zipf distributions (#1184) This breaks serialization compatibility with older versions.

... (truncated)

Changelog

Sourced from rand_distr's changelog.

[0.6.0] — 2026-02-10

  • Bump to MSRV 1.85.0 and Edition 2024 in line with rand (#28)
  • Update rand to version 0.10.0 (#31, #48)

Additions

  • MultiDistribution trait to sample more efficiently from multi-dimensional distributions (#18)
  • Add WeightedAliasIndex::weights() to reconstruct the original weights in O(n) (#25)
  • ConstMultiDistribution trait as support for fixed-dimension distributions (#29)

Changes

  • Moved Dirichlet into the new multi module and implement MultiDistribution for it (#18)
  • Dirichlet no longer uses const generics, which means that its size is not required at compile time. Essentially a revert of [rand#1292]. (#30)

Fixes

  • Fix Geometric::new for small p > 0 where 1 - p rounds to 1 (#36)
  • Use direct-minimal-versions (#38)
  • Fix panic in FisherF::new on almost zero parameters (#39)
  • Fix panic in NormalInverseGaussian::new with very large alpha; this is a Value-breaking change (#40)
  • Fix hang and debug assertion in Zipf::new on invalid parameters (#41)
  • Fix panic in Binomial::sample with n ≥ 2^63; this is a Value-breaking change (#43)
  • Error instead of producing -inf output for Exp when lambda is -0.0 (#44)
  • Avoid returning NaN from Gamma::sample; this is a Value-breaking change and also affects ChiSquared and Dirichlet (#46)

[0.5.1]

Testing

  • Added building the crate to CI

Fixes

  • Fix missing import for no_std builds

Coupled to #66: rand_distr 0.4 -> 0.6 pulls rand 0.9, which is a breaking bump the code does not yet compile against (StandardNormal sampling and the distributions module moved). Needs the same deliberate rand 0.9 migration with a sampler-determinism check rather than an auto-merge. Holding until #66's migration lands.

Closing alongside #66: the rand_distr 0.6 bump pulls the same breaking rand 0.9/0.10 line into the sampler, so it needs the same deliberate determinism-checked migration rather than an auto-merge. Declining for now; will revisit as a focused migration.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
