Struct dflow_sdk::instructions::CloseRetailDataAccount

pub struct CloseRetailDataAccount<'info> {
    pub retail_data_account: Account<'info, RetailDataAccount>,
    pub retail_account_owner: AccountInfo<'info>,
    pub system_program: AccountInfo<'info>,
}

This instruction closes the retail trader’s data account. When retail traders wish to close their account, and regain the lamports used to allocate the space for their data account, they can call this instruction. Retail traders may not close their account if they have open orders, and must wait for the orders to be filled, or cancel them.

Fields

retail_data_account: Account<'info, RetailDataAccount>

The retail data account holds state specific to the retail trader. This account is being closed, and the destination of the lamports will be the retail_account_owner account. This account is expected to be mutable

retail_account_owner: AccountInfo<'info>

The public key of the retail trader. 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 CloseRetailDataAccount<'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 CloseRetailDataAccount<'info> where
    'info: 'info, 

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

program_id is the currently executing program.

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

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

impl<'info> ToAccountMetas for CloseRetailDataAccount<'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.
