Feature Spec

Add the following methods:

  • Array.deepCopyMut
  • Map.deepCopyMut
  • Set.deepCopyMut
  • MutArray.deepCopy
  • MutMap.deepCopy
  • MutSet.deepCopy

These allow you to recursively copy data to ensure that the results don't share any reference with the original data.

Use Cases

For cases where shallow copying is not enough

Contributor guide

Research direction
Study the existing shallow copy methods for Array, Map, Set and their mutable counterparts in the Wing standard library. Implement recursive deep copy logic following the same pattern and ensure no shared references.
