1.1.0

Released 2022-02-09.

Added

  • Added the Unstructured::ratio method to generate a boolean that is true at the given rate.

  • Added the Unstructured::arbitrary_loop method to call a function an arbitrary number of times.

1.0.3

Released 2021-11-20.

Fixed

  • Fixed documentation for Unstructured::fill_bytes. We forgot to update this way back in #53 when the behavior changed.

1.0.2

Released 2021-08-25.

Added

  • Arbitrary impls for HashMaps and HashSets with custom Hashers #87

1.0.1

Released 2021-05-20.

Added

  • Arbitrary impls for NonZeroX types #79
  • Arbitrary impls for all arrays using const generics #55
  • Arbitrary impls for Ipv4Addr and Ipv6Addr #84

Fixed

  • Use fewer bytes for Unstructured::int_in_range() #80
  • Use correct range for char generation #83

1.0.0

Released 2020-02-24.

See 1.0.0-rc1 and 1.0.0-rc2 for changes since 0.4.7, which was the last main line release.

1.0.0-rc2

Released 2021-02-09.

Added

  • The Arbitrary trait is now implemented for &[u8]. #67

Changed

  • Rename Unstructured#get_bytes to Unstructured#bytes. #70
  • Passing an empty slice of choices to Unstructured#choose returns an error. Previously it would panic. 71

1.0.0-rc1

Released 2020-11-25.

Added

  • The Arbitrary trait is now implemented for &str. #63

Changed

  • The Arbitrary trait now has a lifetime parameter, allowing Arbitrary implementations that borrow from the raw input (e.g. the new &str implementaton). The derive(Arbitrary) macro also supports deriving Arbitrary on types with lifetimes now. #63

Removed

  • The shrink method on the Arbitrary trait has been removed.

    We have found that, in practice, using internal reduction via approaches like cargo fuzz tmin, where the raw input bytes are reduced rather than the T: Arbitrary type constructed from those raw bytes, has the best efficiency-to-maintenance ratio. To the best of our knowledge, no one is relying on or using the Arbitrary::shrink method. If you are using and relying on the Arbitrary::shrink method, please reach out by dropping a comment here and explaining how you're using it and what your use case is. We'll figure out what the best solution is, including potentially adding shrinking functionality back to the arbitrary crate.

0.4.7

Released 2020-10-14.

Added

  • Added an optimization to avoid unnecessarily consuming bytes from the underlying data when there is only one possible choice in Unstructured::{int_in_range, choose, etc..}.

  • Added license files to the derive crate.

Changed

  • The Arbitrary implementation for std::time::Duration should now be faster and produce durations with a more-uniform distribution of nanoseconds.

0.4.6

Released 2020-08-22.

Added

  • Added the Unstructured::peek_bytes method.

Changed

  • Test case reduction via cargo fuzz tmin should be much more effective at reducing the sizes of collections now. (See #53 and the commit messages for details.)

  • Fuzzing with mutation-based fuzzers (like libFuzzer) should be more efficient now. (See #53 and the commit messages for details)

0.4.5

Released 2020-06-18.

Added

  • Implement Arbitrary for zero length arrays.
  • Implement Arbitrary for Range and RangeInclusive.

0.4.4

Released 2020-04-29.

Fixed

  • Fixed the custom derive for enums when used via its full path (like #[derive(arbitrary::Arbitrary)] rather than like #[derive(Arbitrary)]).

0.4.3

Released 2020-04-28.

Fixed

  • Fixed the custom derive when used via its full path (like #[derive(arbitrary::Arbitrary)] rather than like #[derive(Arbitrary)]).

0.4.2

Released 2020-04-17.

Changed

  • We forgot to release a new version of the derive_arbitrary crate last release. This release fixes that and so the synstructure dependency is finally actually removed in the cargo releases.

0.4.1

Released 2020-03-18.

Removed

  • Removed an internal dependency on the synstructure crate when the derive feature is enabled. This should not have any visible downstream effects other than faster build times!

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.
