Struct CheckPermission

pub struct CheckPermission<'info> {
    pub sysvar_instructions: UncheckedAccount<'info>,
    pub permission: UncheckedAccount<'info>,
    pub router: UncheckedAccount<'info>,
    pub config_router: UncheckedAccount<'info>,
    pub express_relay_metadata: Account<'info, ExpressRelayMetadata>,
}

Fields

sysvar_instructions: UncheckedAccount<'info>

CHECK: this is the sysvar instructions account.

permission: UncheckedAccount<'info>

CHECK: this is the permission key. Often the permission key refers to an on-chain account storing the opportunity; other times, it could refer to the 32 byte hash of identifying opportunity data. We include the permission as an account instead of putting it in the instruction data to save transaction size via caching in case of repeated use.

router: UncheckedAccount<'info>

CHECK: this is the router address.

config_router: UncheckedAccount<'info>

CHECK: this cannot be checked against ConfigRouter bc it may not be initialized.

express_relay_metadata: Account<'info, ExpressRelayMetadata>

Trait Implementations

impl<'info> Accounts<'info, CheckPermissionBumps> for CheckPermission<'info>

where 'info: 'info,

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

where 'info: 'info,

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

program_id is the currently executing program.

impl<'info> Bumps for CheckPermission<'info>

where 'info: 'info,

type Bumps = CheckPermissionBumps

Struct to hold account bump seeds.

impl<'info> ToAccountInfos<'info> for CheckPermission<'info>

where 'info: 'info,

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

impl<'info> ToAccountMetas for CheckPermission<'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.
