Fields

searcher: Signer<'info>

Searcher is the party that fulfills the quote request

user: Signer<'info>

User is the party that requests the quote

searcher_ta_mint_searcher: Box<InterfaceAccount<'info, TokenAccount>>

searcher_ta_mint_user: Box<InterfaceAccount<'info, TokenAccount>>

user_ata_mint_searcher: Box<InterfaceAccount<'info, TokenAccount>>

user_ata_mint_user: Box<InterfaceAccount<'info, TokenAccount>>

router_fee_receiver_ta: UncheckedAccount<'info>

Router fee receiver token account: the referrer can provide an arbitrary receiver for the router fee CHECK: we check this account manually since it can be uninitialized if the fee is 0

relayer_fee_receiver_ata: UncheckedAccount<'info>

CHECK: we check this account manually since it can be uninitialized if the fee is 0

express_relay_fee_receiver_ata: UncheckedAccount<'info>

CHECK: we check this account manually since it can be uninitialized if the fee is 0

mint_searcher: Box<InterfaceAccount<'info, Mint>>

mint_user: Box<InterfaceAccount<'info, Mint>>

mint_fee: Box<InterfaceAccount<'info, Mint>>

CHECK: we check that this is set correctly based on the fee token manually since the V2 arguments are incompatible on the wire

token_program_searcher: Interface<'info, TokenInterface>

token_program_user: Interface<'info, TokenInterface>

token_program_fee: Interface<'info, TokenInterface>

CHECK: we check that this is set correctly based on the fee token manually since the V2 arguments are incompatible on the wire

express_relay_metadata: Box<Account<'info, ExpressRelayMetadata>>

Express relay configuration

relayer_signer: Signer<'info>

Trait Implementations

impl<'info> Accounts<'info, SwapBumps> for Swap<'info>

where 'info: 'info,

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

where 'info: 'info,

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

program_id is the currently executing program.

impl<'info> Bumps for Swap<'info>

where 'info: 'info,

type Bumps = SwapBumps

Struct to hold account bump seeds.

impl<'info> ToAccountInfos<'info> for Swap<'info>

where 'info: 'info,

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

impl<'info> ToAccountMetas for Swap<'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.
