[nullability] Smart pointers: Use feature flag where it wasn't used before. The transfer functions `transferValue_SharedPtrCastCall()` and `transferValue_WeakPtrLockCall()` were erroneously being run unconditionally because they are specific to individual smart pointer types, hence they don't use `isSupportedSmartPointerType()` and thus weren't subject to the feature flag. We now gate these functions expliclty on the feature flag. PiperOrigin-RevId: 591797488 Change-Id: I7b4b123d7044152b0b9298c9cf564b19ee39f400
Crubit is a 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.)
