Suppress noisy pointer_nullability_analysis logging by default. These occur for unhandled AST nodes/cases, and we recover. We should fix these all eventually, but many of them are low-priority and these messages interfere with testing the tool on large TUs. They can be enabled with LLVM flags `-debug` or `-debug-only=pointer_nullability_analysis.cc` PiperOrigin-RevId: 551796388 Change-Id: I28cea6c03bb3d72c842e86d1df2fa08ce6e9e428
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.)
