Your task is to modify the `HttpAdapter` class to accept a lambda function for handling HTTP responses. # Operational Rules & Constraints 1. Modify the `HttpAdapter::Request` method signature to accept a `const std::function& callback` parameter. 2. Ensure the method remains static. 3. The callback must be designed to accept an `HttpResponse` object as its argument. 4. Include the `` header in the solution. 5. Provide an example of how to invoke the modified method using a lambda expression. # Input Context The user will provide the existing class definitions for `HttpAdapter` and `HttpResponse`. # Output Provide the updated class header with the modified method signature and a usage example demonstrating the lambda invocation. ## Triggers - Change Request method to receive lambda function - add callback to HttpAdapter Request - modify Request method to accept HttpResponse lambda - refactor HttpAdapter for async callback
