0.4.0

Released 2020-01-22.

This is technically a breaking change, but we expect that nearly everyone should be able to upgrade without any compilation errors. The only exception is if you were implementing the Arbitrary::size_hint method by hand. If so, see the "changed" section below and the API docs for Arbitrary::shrink for details.

Added

Changed

  • The Arbitrary::size_hint signature now takes a depth: usize parameter. This should be passed along unmodified to any nested calls of other size_hint methods. If you're implementing size_hint for a recursive type (like a linked list or tree) or a generic type with type parameters, you should use the new arbitrary::size_hint::recursion_guard helper function.

Fixed

  • Fixed infinite recursion in generated size_hint implementations from #[derive(Arbitrary)] for recursive types.

0.3.2

Released 2020-01-16.

Changed

  • Updated the custom derive's dependencies.

0.3.2

Released 2020-01-15.

Fixed

  • Fixed an over-eager assertion condition in Unstructured::int_in_range that would incorrectly trigger when given valid ranges of length one.

0.3.1

Released 2020-01-14.

Fixed

  • Fixed some links and version numbers in README.

0.3.0

Released 2020-01-14.

Added

  • Added the "derive" cargo feature, to enable #[derive(Arbitrary)] for custom types. Enabling this feature re-exports functionality from the derive_arbitrary crate.
  • The custom derive for Arbitrary implements the shrink method for you now.
  • All implementations of Arbitrary for std types implement shrinking now.
  • Added the Arbitrary::arbitrary_take_rest method allows an Arbitrary implementation to consume all of the rest of the remaining raw input. It has a default implementation that forwards to Arbitrary::arbitrary and the custom derive creates a smart implementation for your custom types.
  • Added the Arbitrary::size_hint method for hinting how many raw bytes an implementation needs to construct itself. This has a default implementation, but the custom derive creates a smart implementation for your custom types.
  • Added the Unstructured::choose method to choose one thing among a set of choices.
  • Added the Unstructured::arbitrary_len method to get an arbitrary length for a collection of some arbitrary type.
  • Added the Unstructured::arbitrary_iter method to create an iterator of arbitrary instance of some type.

Changed

  • The Arbitrary trait was simplified a bit.
  • Unstructured is a concrete type now, not a trait.
  • Switched to Rust 2018 edition.

Removed

  • RingBuffer and FiniteBuffer are removed. Use Unstructured instead.

Fixed

  • Better Arbitrary implementation for char.
  • Better Arbitrary implementation for String.
