需要帮助建立一个从Master Edition NFT创建新版本NFT的函数

Question

我目前正在Rust/Anchor-Solana中编写一个Solana Metaplex NFT程序，专门致力于编写逻辑，以从Master Edition NFT创建NFT。

调用MPL_TOKEN_METADATA :: MINT_NEW_EDITION_FOM_MASTER_EDITION_EDITION_VIA_TOKEN指令时，我发现它同时需要Metadata 和code> metadata_mint字段 field as a in as gruments。鉴于，在Metaplex文档上，似乎只需要主记录元数据帐户。

问题：

我应该将哪个帐户密钥或值放入这些字段（metadata和metadata_mint），为什么？

代码：

pub fn create_new_edition_nft(
        ctx: Context<CreateNewEdition>,
        edition: u64,
    ) -> Result<()> {
        let edition_infos = vec![
            ctx.accounts.token_program.to_account_info(),
            ctx.accounts.new_metadata.to_account_info(),
            ctx.accounts.new_edition.to_account_info(),
            ctx.accounts.master_edition.to_account_info(),
            ctx.accounts.new_mint.to_account_info(),
            ctx.accounts.new_mint_authority.to_account_info(),
            ctx.accounts.payer.to_account_info(),
            ctx.accounts.token_account_owner.to_account_info(),
            ctx.accounts.token_account.to_account_info(),
            ctx.accounts.new_metadata_update_authority.to_account_info(),
            ctx.accounts.metadata.to_account_info(),
            ctx.accounts.system_program.to_account_info(),
            ctx.accounts.rent.to_account_info(),
        ];
        msg!("Edition Account Infos Assigned");
        invoke(&mint_new_edition_from_master_edition_via_token(
            ctx.accounts.token_program.key(),ctx.accounts.new_metadata.key(),ctx.accounts.new_edition.key(), ctx.accounts.master_edition.key(), ctx.accounts.new_mint.key(),ctx.accounts.new_mint_authority.key(), ctx.accounts.payer.key(), ctx.accounts.token_account_owner.key(), ctx.accounts.token_account.key(), ctx.accounts.new_metadata_update_authority.key(), ctx.accounts.metadata.key(), ctx.accounts.metadata.key(), edition
        ), edition_infos.as_slice())?;

        msg!("A New Edition Nft Minted !!!");
        Ok(())
    }

您正在谈论的Metaplex上的文档是Solana说明的文档，而不是Rust API。他们不同。如果您查看锈蚀代码，您将看到差异。

文档中描述的帐户与代码提供的帐户匹配：

let accounts = vec![
   AccountMeta::new(new_metadata, false),
   AccountMeta::new(new_edition, false),
   AccountMeta::new(master_edition, false),
   AccountMeta::new(new_mint, false),
   AccountMeta::new(edition_mark_pda, false),
   AccountMeta::new_readonly(new_mint_authority, true),
   AccountMeta::new(payer, true),
   AccountMeta::new_readonly(token_account_owner, true),
   AccountMeta::new_readonly(token_account, false),
   AccountMeta::new_readonly(new_metadata_update_authority, false),
   AccountMeta::new_readonly(metadata, false),
   AccountMeta::new_readonly(spl_token::id(), false),
   AccountMeta::new_readonly(solana_program::system_program::id(), false),
   AccountMeta::new_readonly(sysvar::rent::id(), false),
];

上的地址：

    let (edition_mark_pda, _) = Pubkey::find_program_address(
        &[
            PREFIX.as_bytes(),
            program_id.as_ref(),
            metadata_mint.as_ref(),
            EDITION.as_bytes(),
            as_string.as_bytes(),
        ],
        &program_id,
    );

您正在谈论的变量metadata_mint用于计算链条上的dection> dection_mark_pda链条 将此与文档进行比较，您将看到应提供的内容：

pda tor标记创建 - 将检查是否存在预先存在。 （PDA
['metadata'，程序ID，大师元数据薄荷ID，'Edition'，
distion_number]）其中distion_number不是您的版本号码
传递Args，但实际上Edition_number =
地板（EDITAR/EDITAR_MARKER_BIT_SIZE）。

元数据：=主记录元数据帐户

metadata_mint：= =主元数据Mint ID
