Extract class final

Binds a handler parameter to a custom extractor.

The argument is the extractor type, not an instance. Dust emits const MyExtractor().extract(request) and casts the result to the parameter's type, so the analyzer catches an extractor that produces something else.

Future<Todo> create(@Extract(TodosWrite) AuthUser user, @Body() CreateTodo input);
