v0.20.0

What's Changed

New features

• Support writing depfiles from autocxx_gen by @adetaylor in #1012
• Basic support for extern_cpp_type! by @adetaylor in #1008. This allows one set of include_cpp! bindings to delegate a type to another set obindings.

Boring but breaking change

• Split the Within trait into two by @adetaylor in #1013

Bugfixes and documentation

This version includes a lot of restructuring with no intentional functional change, as prep work for eventually landing the next bit of #379.

• Rewrite constructor chapter of book. by @adetaylor in #1000
• Publish integration tests by @adetaylor in #1001
• Switch tests away from deprecated ::make_unique(). by @adetaylor in #1003
• Restructure codegen_rs/fun/mod.rs by @adetaylor in #1002
• Show autocxx_build::Builder::new in docs by @Xaeroxe in #1004
• Improve Builder documentation. by @adetaylor in #1007
• Harmless changes by @adetaylor in #1014
• Doc fix. by @adetaylor in #1016

New Contributors

• @Xaeroxe made their first contribution in #1004

Full Changelog: v0.19.1...v0.20.0

v0.19.1

What's Changed

• This release deprecates the make_unique() functions that were previously created for each constructor, and instead introduces a new Within trait. This will later become the only way of using constructors. (@adetaylor in #997)

Testing improvements

• Do a test run under ASAN on github CI by @adetaylor in #993 (thanks also to @philipcraig )
• Add tests for gen by @bsilver8192 in #913

Full Changelog: v0.19.0...v0.19.1

v0.19.0

Improvements

• Don't spam stderr so much by @adetaylor in #985
• Use miette for nicer syntax errors by @adetaylor in #980. This also removes some long-deprecated functions, so you may need to update your build.rs files.
• Recognize size_t as usize by @adetaylor in #986
• Support array fields within structs by @yshui (thanks!) in #969

Bug fixes

• Fix use of &str in generated C++ code by @adetaylor in #984
• Ignore constructors taking extra default parameters by @adetaylor in #983
• Fix erroneous allocation sizes when using moveit::new::New by @adetaylor in #991
• Fix problem with methods beginning with their class name by @adetaylor in #992

Miscellaneous

• Add test for moving out of UP by @adetaylor in #973

Full Changelog: v0.18.0...v0.19.0

v0.18.0

What's Changed

• Fix a problem when used with the most recent version of syn by @adetaylor in #971
• Roll to moveit 0.5.0. by @adetaylor in #970. This change allows you to move out of a UniquePtr, e.g.

let xyz: UniquePtr<Foo> = ...;
moveit! {
  let stack_xyz = autocxx::moveit::new::mov(xyz);
}

This is technically a breaking change though I doubt anyone much is using the MoveRef trait a lot.
