1.0.61

• Add String::lossy constructors to C++ API, corresponding to from_utf8_lossy and from_utf16_lossy (#984, thanks @benesch)
• Add Vec<T>::truncate to C++ API (#988, thanks @benesch)
• Assert sufficient alignment of const char16_t* passed to a rust::String constructor (#992)

1.0.60

• Optimize the Debug and Display impl of CxxString to eliminate memory allocation (#979)
• Prevent handwritten panicking Drop, PartialEq, PartialOrd, or Hash trait impls from causing UB when called from C++ (#980)
• Add support for codebases that choose to opt in to elided_lifetimes_in_paths lint (#907, #981)

1.0.59

• Add clear() member function to rust::Vec<T> in C++ (#951, thanks @rookboom)

1.0.58

• no_std mode (#969, #970, #971, #972, #973, #974, #975)

  [dependencies]
  cxx = { version = "1.0", default-features = false, features = ["alloc"] }

  A no_alloc mode is also implemented but is not stable yet in this release.

  [dependencies]
  cxx = { version = "1.0", default-features = false }

1.0.57

• Apply --cxx-impl-annotations also to the functions underlying UniquePtr and similar builtin bindings (#967, thanks @adetaylor)

1.0.56

• Pass through doc(hidden) attributes inside the bridge module (#945)

1.0.55

• Fix build script race causing "Failed to create symlink ... File exists (os error 17)" in cxx_build (#938)

1.0.54

• Enable C++ to reserve and read capacity on a rust::String (#924)

• Enable Rust to reserve capacity on a CxxString (#925)

  This is important in APIs that connect bytes-based code in Rust to std::string-based code in C++.

  use bytes::Buf;
  use cxx::let_cxx_string;
  
  fn thing(buf: &mut dyn Buf) {
      let_cxx_string!(string = "");
  
      // handled by helper:
      string.as_mut().reserve(buf.remaining());
      while buf.remaining() > 0 {
          let chunk = buf.chunk();
          string.as_mut().push_bytes(chunk);
          buf.advance(chunk.len());
      }
  
      ffi::thing(string);
  }
  
  // ffi::thing:
  // void thing(std::string& s) {
  //   WriteMessage msg{std::move(s)};
  //   ...
  // }

1.0.53

• Prevent lint inside generated C++ code in projects that build with -Wshadow (#919, thanks @isg)

1.0.52

• Add method to clear a C++ std::string from Rust (#912)
