type Dart_NativeEntryResolver = Option<unsafe extern "C" fn(name: Dart_Handle, num_of_arguments: c_int, auto_setup_scope: *mut bool) -> Dart_NativeFunction>;

Native entry resolution callback.

For libraries and scripts which have native functions, the embedder can provide a native entry resolver. This callback is used to map a name/arity to a Dart_NativeFunction. If no function is found, the callback should return NULL.

The parameters to the native resolver function are: \param name a Dart string which is the name of the native function. \param num_of_arguments is the number of arguments expected by the native function. \param auto_setup_scope is a boolean flag that can be set by the resolver to indicate if this function needs a Dart API scope (see Dart_EnterScope/ Dart_ExitScope) to be setup automatically by the VM before calling into the native function. By default most native functions would require this to be true but some light weight native functions which do not call back into the VM through the Dart API may not require a Dart scope to be setup automatically.

\return A valid Dart_NativeFunction which resolves to a native entry point for the native function.
