Struct dflow_sdk::instructions::CloseAuctionEpochState

pub struct CloseAuctionEpochState<'info> {
    pub auction_epoch_state: Account<'info, AuctionEpochState>,
    pub auction_state_account: Account<'info, AuctionStateAccount>,
    pub owner: AccountInfo<'info>,
    pub system_program: AccountInfo<'info>,
}

This instruction is used to close an AuctionEpochState account. The auction owner can use this instruction to close the AuctionEpochState account for an old epoch that has no open orders or fills pending settlement. The auction owner can also use this instruction close the AuctionEpochState account for the last, current, or next epoch if the auction is in the Draining state.

Fields

auction_epoch_state: Account<'info, AuctionEpochState>

The auction epoch state account holds state specific to an epoch of the auction, if that state must be remembered beyond the duration of that auction epoch. This account is expected to be mutable. This account is being closed, and the destination of the lamports will be the auction_owner account. This account is a PDA generated by the following seeds: the string literal epoch, an unsigned 64 bit integer, an unsigned 64 bit integer. The key of owner must match the field named owner in this account

auction_state_account: Account<'info, AuctionStateAccount>

The auction state account holds state specific to the auction. This account is expected to be mutable. This account is a PDA generated by the following seeds: the string literal auction_state, an unsigned 64 bit integer

owner: AccountInfo<'info>

The account that created the AuctionEpochState account by calling init_auction_epoch_state_account. This account is a signer for the instruction. This account is expected to be mutable

system_program: AccountInfo<'info>

Trait Implementations

impl<'info> Accounts<'info> for CloseAuctionEpochState<'info> where
    'info: 'info, 

fn try_accounts(
    program_id: &Pubkey,
    accounts: &mut &[AccountInfo<'info>],
    ix_data: &[u8],
    __bumps: &mut BTreeMap<String, u8>,
    __reallocs: &mut BTreeSet<Pubkey>
) -> Result<Self>

Returns the validated accounts struct. What constitutes “valid” is program dependent. However, users of these types should never have to worry about account substitution attacks. For example, if a program expects a Mint account from the SPL token program in a particular field, then it should be impossible for this method to return Ok if any other account type is given–from the SPL token program or elsewhere.

impl<'info> AccountsExit<'info> for CloseAuctionEpochState<'info> where
    'info: 'info, 

fn exit(&self, program_id: &Pubkey) -> Result<()>

program_id is the currently executing program.

impl<'info> ToAccountInfos<'info> for CloseAuctionEpochState<'info> where
    'info: 'info, 

fn to_account_infos(&self) -> Vec<AccountInfo<'info>>

impl<'info> ToAccountMetas for CloseAuctionEpochState<'info>

fn to_account_metas(&self, is_signer: Option<bool>) -> Vec<AccountMeta>

is_signer is given as an optional override for the signer meta field. This covers the edge case when a program-derived-address needs to relay a transaction from a client to another program but sign the transaction before the relay. The client cannot mark the field as a signer, and so we have to override the is_signer meta field given by the client.
