    pub(super) get_handle_counters: extern "C" fn() -> &'static HandleCounters,

🔬This is a nightly-only experimental API. (proc_macro_internals #27812)

A client-side RPC entry-point, which may be using a different proc_macro from the one used by the server, but can be invoked compatibly.

Note that the (phantom) I (“input”) and O (“output”) type parameters decorate the Client<I, O> with the RPC “interface” of the entry-point, but do not themselves participate in ABI, at all, only facilitate type-checking.

E.g. Client<TokenStream, TokenStream> is the common proc macro interface, used for #[proc_macro] fn foo(input: TokenStream) -> TokenStream, indicating that the RPC input and output will be serialized token streams, and forcing the use of APIs that take/return S::TokenStream, server-side.
