Fields

searcher: Signer<'info>

Searcher is the party that sends the input token and receives the output token

trader: Signer<'info>

Trader is the party that sends the output token and receives the input token

searcher_input_ta: InterfaceAccount<'info, TokenAccount>

searcher_output_ta: InterfaceAccount<'info, TokenAccount>

trader_input_ata: InterfaceAccount<'info, TokenAccount>

trader_output_ata: InterfaceAccount<'info, TokenAccount>

router_fee_receiver_ta: InterfaceAccount<'info, TokenAccount>

Router fee receiver token account: the referrer can provide an arbitrary receiver for the router fee

relayer_fee_receiver_ata: InterfaceAccount<'info, TokenAccount>

express_relay_fee_receiver_ata: InterfaceAccount<'info, TokenAccount>

mint_input: InterfaceAccount<'info, Mint>

mint_output: InterfaceAccount<'info, Mint>

mint_fee: InterfaceAccount<'info, Mint>

token_program_input: Interface<'info, TokenInterface>

token_program_output: Interface<'info, TokenInterface>

token_program_fee: Interface<'info, TokenInterface>

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

Express relay configuration

Implementations

impl<'info> Swap<'info>

pub fn transfer_swap_fees(&self, args: &SwapArgs) -> Result<PostFeeSwapArgs>

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.
