    }

The canonical on-chain representation of a compressed NFT leaf, hashed to produce the value stored at a tree's leaf node.

V1 is produced by mintV1/mintToCollectionV1 and the legacy instruction family; V2 is produced by mintV2 and adds collectionHash, assetDataHash and flags to support MPL Core collections and freezing/non-transferable assets.

}
- __kind: "V1"
- creatorHash: number[]
  Keccak256 hash of the leaf's creators array.
- dataHash: number[]
  Keccak256 hash of the leaf's metadata (MetadataArgs/MetadataArgsV2).
- delegate: Address
  Current delegate of the leaf (equal to owner when unset).
- id: Address
  Asset id of the leaf, derived from the tree address and nonce.
- nonce: bigint
  Tree-scoped nonce assigned to the leaf when it was minted; part of the asset id derivation.
- owner: Address
  Current owner of the leaf.

}
- __kind: "V2"
- assetDataHash: number[]
  Hash of the leaf's optional off-chain asset data, if any (V2 only).
- collectionHash: number[]
  Hash of the leaf's MPL Core collection reference, if any (V2 only).
- creatorHash: number[]
  Keccak256 hash of the leaf's creators array.
- dataHash: number[]
  Keccak256 hash of the leaf's metadata (MetadataArgs/MetadataArgsV2).
- delegate: Address
  Current delegate of the leaf (equal to owner when unset).
- flags: number
  Packed status bits for the leaf, e.g. frozen and non-transferable (V2 only).
- id: Address
  Asset id of the leaf, derived from the tree address and nonce.
- nonce: bigint
  Tree-scoped nonce assigned to the leaf when it was minted; part of the asset id derivation.
- owner: Address
  Current owner of the leaf.
