Function to print a type and its nullability vector together in standard syntax This will be used in printing test failures, in the analysis logs. (Potentially in diagnosis one day?) It further decouples us from the nullability vector data structure. The main tradeoff is complexity: this is a third algorithm (after transfer & NullabilityWalker) that matches the data structure to AST nodes, and the three must be kept in sync.

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.)
