Include default move constructor in the generated C++ bindings. In the past we decided to hold off with generating C++ assignment operators to keep our options open for dealing with various memory safety concerns. At this point we've decided to accept the risks and want to enable the assignment operators. PiperOrigin-RevId: 538198331
Crubit is an experimental bidirectional bindings generator for C++ and Rust.
Please don‘t use, this is an experiment and we don’t yet know where will it take us. There will be breaking changes without warning. Unfortunately, we can't take contributions at this point.
Crubit allows for C++ code and Rust code to call each other without manually wrapping the APIs in an FFI-friendly interop layer. For example, a C++ function like this:
bool IsAbsPath(std::string_view path);
... becomes callable from Rust as if it were defined as:
pub fn IsAbsPath(path: std::string_view) -> bool {...}
Crubit automatically generates ABI-compatible bindings for structs (which can be passed both by value and by reference), functions, and methods, for a large variety of types. (Trivial types, nontrivial types, templated types, etc.)
