[#67](https://github.com/rust-fuzz/arbitrary/pull/67) + +### Changed + +* Rename `Unstructured#get_bytes` to `Unstructured#bytes`. [#70](https://github.com/rust-fuzz/arbitrary/pull/70) +* Passing an empty slice of choices to `Unstructured#choose` returns an error. Previously it would panic. [71](https://github.com/rust-fuzz/arbitrary/pull/71) + +-------------------------------------------------------------------------------- + +## 1.0.0-rc1 + +Released 2020-11-25. + +### Added + +* The `Arbitrary` trait is now implemented for `&str`. [#63](https://github.com/rust-fuzz/arbitrary/pull/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](https://github.com/rust-fuzz/arbitrary/pull/63) + +### Removed + +* The `shrink` method on the `Arbitrary` trait has been removed. + + We have found that, in practice, using [internal reduction](https://drmaciver.github.io/papers/reduction-via-generation-preview.pdf) 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](https://github.com/rust-fuzz/arbitrary/issues/62) 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](https://github.com/rust-fuzz/arbitrary/pull/53) and the commit messages + for details.) + +* Fuzzing with mutation-based fuzzers (like libFuzzer) should be more efficient + now. (See [#53](https://github.com/rust-fuzz/arbitrary/pull/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`](https://docs.rs/arbitrary/0.4.0/arbitrary/trait.Arbitrary.html#method.size_hint) +for details. + +### Added + +* Added [the `arbitary::size_hint::recursion_guard` helper + function][recursion_guard] for guarding against infinite recursion in + `size_hint` implementations for recursive types. + +### 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][recursion_guard]. + +### Fixed + +* Fixed infinite recursion in generated `size_hint` implementations + from `#[derive(Arbitrary)]` for recursive types. + +[recursion_guard]: https://docs.rs/arbitrary/0.4.0/arbitrary/size_hint/fn.recursion_guard.html + +-------------------------------------------------------------------------------- + +## 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`. + +-------------------------------------------------------------------------------- + +## 0.2.0 + +-------------------------------------------------------------------------------- + +## 0.1.0 |
