pub unsafe fn create_cpp_to_rust_project_state_context(
callback_target: NonNull<Box<dyn ProjectStateContext>>
) -> NonNull<ProjectStateContext>
Expand description
Creates a ProjectStateContext
object on C++ side and returns a pointer to it.
This function is provided because Rust structs can’t implement C++ virtual base classes.
Example
See create_cpp_to_rust_control_surface()
. Usage is very similar.
Cleaning up
In order to avoid memory leaks, you must take care of removing the C++ counterpart
ProjectStateContext by calling delete_cpp_project_state_context()
.
Safety
This function is highly unsafe. Better use the medium-level API instead.
