objwalker

Objwalker is a Go library that enables deep traversal of arbitrary object structures using reflection. It recursively walks through struct fields, slice/array items, and map keys/values, providing a callback mechanism for inspecting or manipulating each element in the object tree.

Key Features

• Recursive Traversal — Automatically walks through nested structs, slices, arrays, and maps.
• Callback-Based Inspection — Invokes a user-defined callback function for each object in the tree, passing detailed WalkInfo.
• Loop Protection — Prevents infinite recursion on cyclic data structures, with an option to disable this protection.
• Detailed WalkInfo — Provides reflection.Value, direct data pointers, parent references, and other metadata for each visited object.
• Flexible Data Handling — Supports reading and manipulating underlying data through reflection and direct pointers.

Philosophy

Objwalker is designed to simplify deep inspection and manipulation of complex Go data structures, emphasizing safety with built-in loop protection while offering low-level access for advanced use cases.
