Bumps arbitrary from 1.4.2 to 1.5.0.

Changelog

Sourced from arbitrary's changelog.

1.5.0

Released 2026-10-05.

Added

• Added support for deriving Arbitrary for types with raw identifiers.

Changed

• Updated derive_arbitrary to syn 3. This raises the MSRV from 1.63.0 to 1.71.0, which is the MSRV of syn 3.

Fixed

• Fixed soundness when generating arrays.
• Fixed nonzero integer generation to always produce a nonzero value.
• Updated derive_arbitrary to include fixes for fully qualified paths.
