func DeepCopy ¶

func DeepCopy(v any) any

DeepCopy creates an optimized deep copy of any value.

Optimizations:

• Returns nil for nil input (no allocation)
• Returns empty literals for empty collections (no heap allocation)
• Fast path for primitive types (no recursion needed)
• Pre-sizes destination maps and slices to avoid growth reallocations

This function is safe for concurrent use and handles nested structures including maps, slices, and primitives.

Note: For type-safe copying of map[string]any, use DeepCopyMap instead.

func DeepCopyMap ¶

func DeepCopyMap(m map[string]any) map[string]any

DeepCopyMap creates a type-safe deep copy of a map[string]any. This is a convenience wrapper around DeepCopy that eliminates the need for type assertions.

Example:

m := map[string]any{"key": "value"}
copied := util.DeepCopyMap(m)  // Returns map[string]any directly
