Compute the constraints on inferable slots used to compute other values' nullabilities once per function. Previously was once per callExpr and once per return statement in the CFG. This also reduces the complexity of arguments that are wired through collection functions. PiperOrigin-RevId: 575950446 Change-Id: I07bd5d2aeb4b3026432ad3fce2940e1188a37ebb
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.)
