v0.16.0

What's Changed

• The main improvement here is continued support for the moveit crate, and its ability to move/copy construct non-trivial C++ objects around on the Rust stack. The support is still not finished - you still can't, for instance, pass such objects by value into existing C++ functions - but it's further on. In this version you can move non-trivial C++ objects around on the Rust stack, make copies etc. subject to the availability of move/copy constructors on the C++ side.
  • Implement CopyNew trait in #752
  • Implement MoveNew trait in #752
  • Implement Drop trait in #758. (Previously stack-allocated C++ objects didn't get their destructors called)
  • Bump up to a new version of moveit which allows us to emplace into UniquePtr (#757). Note that there is a known bug/limitation here, #772
  • Correctly identify deleted move constructors in #738
  • Hopefully (and this is the big big) identify and populate all the implicit constructors that C++ standards specify - #760. This is error-prone so if there are problems, this is probably why, and a new block_constructors! directive is added on the assumption that I've messed something up here and a workaround is needed.
• Another significant improvement is that all the autogenerated type names for AutocxxConcrete types are now more descriptive by @adetaylor in #764
• Correctly spot types which are abstract due to private pure virtual functions by @adetaylor in #750
• Add cxx to dependencies in Readme example by @psmit in #741
• Update s2geometry URI by @adetaylor in #746
• Regularize bindgen annotations. by @adetaylor in #734. This is a step towards potentially being able to upstream some of these annotations into the upstream bindgen, though it's a long way off still
• A couple of fixes for the autocxx-reduce pipeline by @adetaylor in #747, #749
• Fixing comments in non-trivial C++ types example. by @adetaylor in #748
• Fixing some garbage collection issues in #759
• Some miscellaneous test changes
  • Add additional test for issue 486. by @adetaylor in #736, #737
  • Switch test logging dependencies due to deprecation. by @adetaylor in #740

New Contributors

• @psmit made their first contribution in #741

Full Changelog: v0.13.0...v0.13.1

v0.13.0

• Subclass improvements:
  • Allow subclassing of C++ classes in namespaces.
  • Support arbitrary constructors for superclasses.
  • Simplify subclass default traits.
  • Some rejigging of the directives/macro names. Breaking change but only if you already used the subclass support.
  • Allow unit structs to be subclasses.
• Improve specificity of error messages around missing dependencies.
• Provide the option to suppress system headers.
• Provide an autodiscovery mode which attempts to spot use of ffi:: to avoid any allowlist at all.
• Provide #[extern_rust_fun] and #[extern_rust_type] attribute macros to allow exporting of arbitrary Rust code to C++.
• Bump bindgen version.
• Make compatible with resolver = 2.
• Breaking change Deprecated some of the builder methods and replaced them with, err, a Builder builder.

v0.12.0

• Revised minimum Rust version to 1.54
• Bumped env_logger and removed dependency on indoc to make the transitive dependency tree smaller
• New APIs in autocxx_build; old ones still exist but are deprecated - move to the new ones
• Synthesize make_unique for types with default constructors (fixes #122)
• Add an experimental "dynamic discovery" mode (see autocxx_build::Builder::auto_allowlist) which enables you to remove the generate directives
• Subclasses:
  • Simplified example by adding prelude and some derive macros
  • Removed the need to explicitly call a C++ peer constructor; the subclass codegen now does this automatically unless there are multiple or complex constructors in which case you'll need to implement a trait to choose
  • Improved panics on re-entrancy and similar error states
  • Filed issues for all known limitations and mentioned in documentation
• Much documentation
• Filenames of generated .rs files on disk have changed - they're no longer based on a hash of the directives. This should reduce filesystem pollution through leaking old versions.

v0.11.2

• Minimum Rust version now 1.55
• Added rust_type! to allow passing references to Rust types within C++ APIs
• Added support for rust::Box to allow passing opaque Rust types into and out of C++ APIs
• Added very early support for creating Rust subclasses of C++ superclasses, subject to a bunch of constraints. See examples/subclass/src/main.rs.
• Upgrade to cxx 1.0.54

v0.11.1

• Latest bindgen code, fixing a panic with 'unable to get type information'
• Derive Copy for the C integer wrappers
• Another example
• Add an official way to make strings

v0.11.0

• Spot inner types whose outer type contains __ and ignore them
• Ignore APIs where bindgen wants &u8 used as a receiver
• Support std::shared_ptr and std::weak_ptr
• Documentation update.
