InterfaceDescription

FragmentPosition

Represents a position within a fragment using child index and offset.

This interface provides an alternative way to specify positions within a fragment, using the index of a child node and an offset within that child, rather than an absolute position. This is particularly useful for operations that need to identify both which child node contains a position and where within that node the position lies.

Example

typescript
// For a fragment with children of sizes [5, 3, 7]
// Position 8 would be:
const diffIndex: DiffIndex = {
  index: 2, // Third child (0-indexed)
  offset: 5, // Starts at position 5 (5 + 3)
};
