Function grpcio_sys::grpc_register_plugin

pub unsafe extern "C" fn grpc_register_plugin(
    init: Option<unsafe extern "C" fn()>, 
    destroy: Option<unsafe extern "C" fn()>
)

Registers a plugin to be initialized and destroyed with the library.

The \a init and \a destroy functions will be invoked as part of \a grpc_init() and \a grpc_shutdown(), respectively. Note that these functions can be invoked an arbitrary number of times (and hence so will \a init and \a destroy). It is safe to pass NULL to either argument. Plugins are destroyed in the reverse order they were initialized.
