• 📝 PR summary: This PR introduces significant changes to the semantic router, including the addition of a LayerConfig class for initializing a RouteLayer, the ability to save and load routers to/from JSON or YAML files, and the addition of a RouteChoice class. It also includes changes to the Route class to allow for function schemas and calls, and modifications to the RouteLayer class to use the new LayerConfig class and to add routes to the routes list when the add method is called.
• 📌 Type of PR: Enhancement
• 🧪 Relevant tests added: No

PR Feedback

💡 General suggestions: The PR introduces several new features and improvements, which are generally well-implemented. However, it would be beneficial to include tests for these new features to ensure they work as expected. Additionally, the PR could benefit from more detailed comments explaining the purpose and functionality of the new classes and methods, especially for the LayerConfig and RouteChoice classes.

relevant file	semantic_router/layer.py
suggestion	Consider handling the case where the encoder type is not recognized in the __init__ method of the LayerConfig class. Currently, if an unrecognized encoder type is provided, the method will not set an encoder name and will not raise an error, which could lead to problems later on. [important]
relevant line	elif encoder_type == EncoderType.HUGGINGFACE:

---

relevant file	semantic_router/layer.py
suggestion	In the from_file method of the LayerConfig class, consider moving the is_valid check to the beginning of the method. This way, the method can exit early if the provided file is not valid, avoiding unnecessary processing. [medium]
relevant line	if is_valid(route_config_str):

relevant file	semantic_router/layer.py
suggestion	In the __call__ method of the RouteLayer class, consider handling the case where the top_class is not found in the routes. Currently, if the top_class is not found, the method will raise an IndexError. [important]
relevant line	route = [route for route in self.routes if route.name == top_class][0]

relevant file	semantic_router/route.py
suggestion	In the __call__ method of the Route class, consider handling the case where the function schema is provided but the function call fails. Currently, if the function call fails, the method will raise an error and not return a RouteChoice. [medium]
relevant line	extracted_inputs = function_call.extract_function_inputs(
