Expand description
Compile-time descriptor of a fidius interface used by the Python loader.
The cdylib path doesn’t need any of this: the dylib carries its own
PluginRegistry + vtable that the host introspects at load time. A
Python plugin doesn’t have a vtable; the host needs an out-of-band hint
about which method names exist on the trait, in what order, and with
which wire mode. The #[plugin_interface] macro emits a
PythonInterfaceDescriptor const into its companion module to provide
exactly that.
The descriptor is 'static-shaped (string slices, slice of structs) so
it can sit in the binary’s .rodata and be referenced freely.
