Struct dflow_sdk::instructions::UpdateEncryptionKeyInstruction

pub struct UpdateEncryptionKeyInstruction<'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 updates the market maker’s 256-bit X25519 public key. Retail traders use the market maker’s 256-bit X25519 public key to encrypt their order details when routing orders to the market maker. This instruction updates the market maker’s X25519 public key.

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 mutable

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 UpdateEncryptionKeyInstruction<'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 UpdateEncryptionKeyInstruction<'info> where
    'info: 'info, 

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

program_id is the currently executing program.

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

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

impl<'info> ToAccountMetas for UpdateEncryptionKeyInstruction<'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.
