Refactoring: deduplication: `format_param_types_for_cc`. Quite similar code was used by both `format_fn` and `format_thunk_decl` to format function parameters. The duplication would get somewhat worse after adding support for function pointers (which adds a 3rd place where parameter types need to be formatted + requires formatting them with a future/new TypeLocation). Because of the above, this CL extracts the shared code into `format_param_types_for_cc`. PiperOrigin-RevId: 524116023
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.)
