What is the performance impact of using @late_nav?

The first call incurs an O(path-length) compilation cost, but subsequent calls are O(1) due to inline caching, making it suitable for performance-critical applications.

What is a Navigator in this context?

A Navigator is a compiled path expression that encodes navigation steps and constraints, allowing for efficient, reusable selection and transformation of data within nested structures.

How are 3-MATCH constraints used?

The 3-MATCH system verifies that the constraints defined in a path are logically satisfiable before execution, detecting infeasible combinations early and optimizing the filtering order.

How does bidirectional navigation benefit development?

Bidirectionality allows you to use the exact same path logic to both find (select) data and modify (transform) it, reducing code duplication and potential errors in complex data workflows.

Data Science & ML

Enables high-performance bidirectional navigation and transformation of complex nested data structures using compiled path expressions and constraint logic.

About

The Specter Navigator Gadget integrates Clojure-inspired Specter navigation with compiled path objects and 3-MATCH constraint satisfaction to provide a unified architecture for structure traversal. It allows developers to define 'Navigators' that compile path expressions into optimized, cached execution units capable of both selecting and transforming data. By incorporating 3-SAT-like verification, it ensures that path compositions are satisfiable before execution, making it an essential tool for manipulating complex topological data, S-expressions, and deeply nested dictionaries with minimal performance overhead.
