model¶

Base model implementation for AWS Lambda objects.

This module provides the foundational data models for the AWS Lambda library, implementing common patterns for representing and interacting with AWS Lambda resources. The models follow three key design patterns:

Raw Data Storage Pattern:

All models store the original API response data in a _data attribute, treating the API response schema as potentially unstable. Properties provide a stable interface for accessing the underlying data, making the code more resilient to API changes.

Property-Based Access Pattern:

All attributes are exposed through properties rather than direct instance attributes. This approach allows for lazy loading, data validation, and type conversion while maintaining a clean public interface.

Core Data Extraction Pattern:

Each model implements a core_data property that returns a standardized, minimal representation of the object. This provides a consistent way to access essential information across different model types.

These models are designed to be instantiated by the API client methods, not directly by users of the library. They provide a Pythonic interface to the JSON data returned by the native boto3 AWS Lambda API.
