How can I specify overloads for a setter for a def_prop_rw?

[bethebunny]

In some cases my C++ types have multiple setters that support different input types, and I'm binding these in Python as properties. How can I supply an overload set as my setter? Is there an easy way that shows the overloads in stubs correctly, or would I need to build the function + signature myself as a lambda that internally uses nb::try_cast etc?

You could bind a std::variant or write a setter for, e.g., nb::object and then use a sequence of try_cast calls. Yet another option could be to define a custom type that supports implicit conversions. Overloading properties directly the way you suggest is not supported by nanobind.
