go-deepcopy
A fast, feature-rich deep-copy library for Go with support for complex type conversions and custom copying behaviors.
What is go-deepcopy?
go-deepcopy is a Go library that performs fast and flexible deep copying of data structures. It solves the problem of manually copying complex nested types by providing a reflection-based API that supports copying between different types, custom field mappings, and post-copy hooks.
Go developers working with complex data structures, serialization, or data transformation tasks, especially those needing to copy data between different struct types or convert types during copying.
Developers choose go-deepcopy for its combination of speed, extensive feature set, and configurability, outperforming many alternative libraries in benchmarks while offering advanced features like zero-to-nil conversion and custom copy methods.
