Struct dflow_sdk::instructions::InitMarketMakerAccountInstruction

pub struct InitMarketMakerAccountInstruction<'info> {
    pub market_maker_data_account: Account<'info, MarketMakerDataAccount>,
    pub market_maker_account_owner: AccountInfo<'info>,
    pub market_maker_whitelist_entry: Account<'info, WhitelistEntry>,
}

This instruction initializes the market maker account The market maker account tracks state specific to the market maker’s market making activities. This instruction must be called prior to a market maker being active on DFlow.

Fields

market_maker_data_account: Account<'info, MarketMakerDataAccount>

The account storing state specific to the market maker. This account must be owned by the DFlow program, and this account must be initialized by calling the initialize market maker instruction. This account is expected to be zeroed out upon the start of instruction processing

market_maker_account_owner: AccountInfo<'info>

The public key of the market maker. This account is a signer for the instruction

market_maker_whitelist_entry: Account<'info, WhitelistEntry>

This account stores the permissions that apply to the market_maker_account_owner. This account is a PDA generated by the following seeds: the string literal whitelist_entry, the public key of the market_maker_account_owner account

Trait Implementations

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

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

program_id is the currently executing program.

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

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

impl<'info> ToAccountMetas for InitMarketMakerAccountInstruction<'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.
