store_wallet: SystemAccount<'info>

The store wallet.

owner: UncheckedAccount<'info>

The owner of the order. CHECK: only used to validate and receive input funds.

receiver: UncheckedAccount<'info>

The receiver of the order. CHECK: only used to validate and receive output funds.

rent_receiver: UncheckedAccount<'info>

The rent receiver of the order. CHECK: only used to validate and receive rent.

user: AccountLoader<'info, UserHeader>

User Account.

referrer_user: Option<AccountLoader<'info, UserHeader>>

Referrer User Account.

order: AccountLoader<'info, Order>

Order to close.

initial_collateral_token: Option<Box<Account<'info, Mint>>>

Initial collateral token.

final_output_token: Option<Box<Account<'info, Mint>>>

Final output token.

long_token: Option<Box<Account<'info, Mint>>>

Long token.

short_token: Option<Box<Account<'info, Mint>>>

Short token.

initial_collateral_token_escrow: Option<Box<Account<'info, TokenAccount>>>

The escrow account for initial collateral tokens.

final_output_token_escrow: Option<Box<Account<'info, TokenAccount>>>

The escrow account for final output tokens.

long_token_escrow: Option<Box<Account<'info, TokenAccount>>>

The escrow account for long tokens.

short_token_escrow: Option<Box<Account<'info, TokenAccount>>>

The escrow account for short tokens.

initial_collateral_token_ata: Option<UncheckedAccount<'info>>

The ATA for initial collateral token of the owner. CHECK: should be checked during the execution.

final_output_token_ata: Option<UncheckedAccount<'info>>

The ATA for final output token of the receiver. CHECK: should be checked during the execution.

long_token_ata: Option<UncheckedAccount<'info>>

The ATA for long token of the receiver. CHECK: should be checked during the execution.

short_token_ata: Option<UncheckedAccount<'info>>

The ATA for initial collateral token of the receiver. CHECK: should be checked during the execution.

system_program: Program<'info, System>

The system program.

token_program: Program<'info, Token>

The token program.

associated_token_program: Program<'info, AssociatedToken>

Trait Implementations

impl<'info> Accounts<'info, CloseOrderBumps> for CloseOrder<'info>

where 'info: 'info,

fn try_accounts( __program_id: &Pubkey, __accounts: &mut &'info [AccountInfo<'info>], __ix_data: &[u8], __bumps: &mut CloseOrderBumps, __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 CloseOrder<'info>

where 'info: 'info,

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

program_id is the currently executing program.

impl<'info> Bumps for CloseOrder<'info>

where 'info: 'info,

type Bumps = CloseOrderBumps

Struct to hold account bump seeds.

impl<'info> ToAccountInfos<'info> for CloseOrder<'info>

where 'info: 'info,

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

impl<'info> ToAccountMetas for CloseOrder<'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.
