Refactor `ReturnValueSlot.Test` to avoid reading destroyed objects. The test wants to check that the object pointed by `slot_ptr` has been destroyed. Before this CL the test would read the `slot_ptr->state` field and assert that it is equal to `kDestroyedState`. Reading an already destroyed object is UB and was caught by MSAN. After this CL, the assertion is done through `destroyed_locations` instead. PiperOrigin-RevId: 551219313 Change-Id: I4a5e085ad6a7ae8943721b93e52197fd11245a1c
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.)
