Fields

enclave: Quote

Represents the state of the quote verifiers enclave.

authority: Pubkey

The authority of the EnclaveAccount which is permitted to make account changes.

attestation_queue: Pubkey

Queue used for attestation to verify a MRENCLAVE measurement.

created_at: i64

The unix timestamp when the quote was created.

is_on_queue: bool

Whether the quote is located on the AttestationQueues buffer.

last_heartbeat: i64

The last time the quote heartbeated on-chain.

reward_escrow: Pubkey

The SwitchboardWallet account containing the reward escrow for verifying quotes on-chain. We should set this whenever the operator changes so we dont need to pass another account and can verify with has_one.

stake_wallet: Pubkey

The SwitchboardWallet account containing the queues required min_stake. Needs to be separate from the reward_escrow. Allows easier 3rd party management of stake from rewards.

success_ewma: Ewma

Tracks the number of successful price attestations.

failure_ewma: Ewma

Tracks the number of failed price attestations (user reported).

gateway_uri: [u8; 64]

URI location of the verifier’s gateway.

_ebuf: [u8; 872]

Reserved.

Implementations

impl VerifierAccountData

pub fn size() -> usize

pub fn new<'info>( quote_account_info: &'info AccountInfo<'info> ) -> Result<Ref<'info, VerifierAccountData>>

Returns the deserialized Switchboard Quote account

Arguments

• quote_account_info - A Solana AccountInfo referencing an existing Switchboard QuoteAccount

Examples

use switchboard_solana::VerifierAccountData;

let quote_account = VerifierAccountData::new(quote_account_info)?;

pub fn new_from_bytes(data: &[u8]) -> Result<&VerifierAccountData>

Returns the deserialized Switchboard Quote account

Arguments

• data - A Solana AccountInfo’s data buffer

Examples

use switchboard_solana::VerifierAccountData;

let quote_account = VerifierAccountData::new(quote_account_info.try_borrow_data()?)?;

Trait Implementations

impl AccountDeserialize for VerifierAccountData

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

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>

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 VerifierAccountData

fn clone(&self) -> VerifierAccountData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VerifierAccountData

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

Formats the value using the given formatter.

impl Discriminator for VerifierAccountData

const DISCRIMINATOR: [u8; 8] = _

fn discriminator() -> [u8; 8]

impl Owner for VerifierAccountData

fn owner() -> Pubkey

impl Zeroable for VerifierAccountData

fn zeroed() -> Self

Calls zeroed.

impl Copy for VerifierAccountData

impl Pod for VerifierAccountData

impl ZeroCopy for VerifierAccountData
