Initialization
Solidity
Section titled “Solidity”constructor() ERC721(DUTCH_AUCTION_COLLECTION_NAME, DUTCH_AUCTION_COLLECTION_SYMBOL){}fun init_module(creator: &signer) { let description = string::utf8(DUTCH_AUCTION_COLLECTION_DESCRIPTION); let name = string::utf8(DUTCH_AUCTION_COLLECTION_NAME); let uri = string::utf8(DUTCH_AUCTION_COLLECTION_URI);
collection::create_unlimited_collection( creator, description, name, option::none(), uri, );}init_module 会先创建一个 collection object,后续所有 token object 都会归属于它。相比 Solidity,这里仍然存在“一次性初始化”步骤,但产物不再是继承了 ERC-721 行为的合约状态机,而是一套链上的 object 结构。
