Fields

authority: Pubkey

The address of the authority which is permitted to add/remove allowed enclave measurements.

mr_enclaves: [[u8; 32]; 32]

Allowed enclave measurements.

oracle_keys: [Pubkey; 128]

The addresses of the quote oracles who have a valid verification status and have heartbeated on-chain recently.

max_quote_verification_age: i64

The maximum allowable time until a EnclaveAccount needs to be re-verified on-chain.

last_heartbeat: i64

The unix timestamp when the last quote oracle heartbeated on-chain.

node_timeout: i64

oracle_min_stake: u64

The minimum number of lamports a quote oracle needs to lock-up in order to heartbeat and verify other quotes.

allow_authority_override_after: i64

mr_enclaves_len: u32

The number of allowed enclave measurements.

oracle_keys_len: u32

The length of valid quote oracles for the given attestation queue.

reward: u32

The reward paid to quote oracles for attesting on-chain.

curr_idx: u32

Incrementer used to track the current quote oracle permitted to run any available functions.

gc_idx: u32

Incrementer used to garbage collect and remove stale quote oracles.

require_authority_heartbeat_permission: u8

require_authority_verify_permission: u8

require_usage_permissions: u8

mint: Pubkey

_ebuf: [u8; 1024]

Reserved.

Implementations

impl QueueAccountData

pub fn size() -> usize

pub fn new<'info>( attestation_queue_account_info: &'info AccountInfo<'info> ) -> Result<Ref<'info, QueueAccountData>, OnDemandError>

Returns the deserialized Switchboard AttestationQueue account

Arguments

• attestation_queue_account_info - A Solana AccountInfo referencing an existing Switchboard AttestationQueue

Examples

use switchboard_solana::QueueAccountData;

let attestation_queue = QueueAccountData::new(attestation_queue_account_info)?;

pub fn new_from_bytes(data: &[u8]) -> Result<&QueueAccountData, OnDemandError>

Returns the deserialized Switchboard AttestationQueue account

Arguments

• data - A Solana AccountInfo’s data buffer

Examples

use switchboard_solana::QueueAccountData;

let attestation_queue = QueueAccountData::new(attestation_queue_account_info.try_borrow_data()?)?;

pub fn has_mr_enclave(&self, mr_enclave: &[u8]) -> bool

pub fn permitted_enclaves(&self) -> Vec<[u8; 32]>

pub fn garbage_collection_node(&self) -> Option<Pubkey>

pub fn idx_of_oracle(&self, oracle: &Pubkey) -> Option<usize>

pub fn oracle_keys(&self) -> Vec<Pubkey>

pub async fn fetch_async( client: &RpcClient, pubkey: Pubkey ) -> Result<Self, OnDemandError>

pub async fn fetch_oracles( &self, client: &RpcClient ) -> Result<Vec<OracleAccountData>, OnDemandError>

Trait Implementations

impl AccountDeserialize for QueueAccountData

fn try_deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes previously initialized account data. Should fail for all uninitialized accounts, where the bytes are zeroed. Implementations should be unique to a particular account type so that one can never successfully deserialize the data of one account type into another. For example, if the SPL token program were to implement this trait, it should be impossible to deserialize a Mint account into a token Account.

fn try_deserialize_unchecked(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes account data without checking the account discriminator. This should only be used on account initialization, when the bytes of the account are zeroed.

impl Clone for QueueAccountData

fn clone(&self) -> QueueAccountData

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueueAccountData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Discriminator for QueueAccountData

const DISCRIMINATOR: [u8; 8] = _

fn discriminator() -> [u8; 8]

impl Owner for QueueAccountData

fn owner() -> Pubkey

impl Zeroable for QueueAccountData

fn zeroed() -> Self

Calls zeroed.

impl Copy for QueueAccountData

impl Pod for QueueAccountData
