AssetId

struct AssetId {
  bytes4 class;
  bytes data;
}

hash

function hash(struct Assets.AssetId assetId) internal pure returns (bytes32)

Calculates Asset ID hash

token

function token(struct Assets.AssetId self) internal pure returns (address)

Extracts token contract address from the Asset ID structure. The address is the common attribute for all assets regardless of their asset class.
