Function: validateCycleAndSelf()

validateCycleAndSelf<TRow>(sourceId, targetId, _position, state): MoveValidationResult

Defined in: src/tree-editor/validators.ts:35

Built-in move validator. Rejects self-moves and moves that would create a cycle (moving a node onto one of its own descendants).

• sourceId is the node being moved.
• targetId is the drop target (or null to move to root).
• position is 'child' | 'before' | 'after' (informational here — the cycle/self checks apply regardless of position).
