Fields

name: [u8; 32]

Name of the queue to store on-chain.

metadata: [u8; 64]

Metadata of the queue to store on-chain.

authority: Pubkey

The account delegated as the authority for making account changes or assigning permissions targeted at the queue.

oracle_timeout: u32

Interval when stale oracles will be removed if they fail to heartbeat.

reward: u64

Rewards to provide oracles and round openers on this queue.

min_stake: u64

The minimum amount of stake oracles must present to remain on the queue.

slashing_enabled: bool

Whether slashing is enabled on this queue.

variance_tolerance_multiplier: SwitchboardDecimal

The tolerated variance amount oracle results can have from the accepted round result before being slashed. slashBound = varianceToleranceMultiplier * stdDeviation Default: 2

feed_probation_period: u32

Number of update rounds new feeds are on probation for. If a feed returns 429s within probation period, auto disable permissions.

curr_idx: u32

Current index of the oracle rotation.

size: u32

Current number of oracles on a queue.

gc_idx: u32

Garbage collection index.

consecutive_feed_failure_limit: u64

Consecutive failure limit for a feed before feed permission is revoked.

consecutive_oracle_failure_limit: u64

Consecutive failure limit for an oracle before oracle permission is revoked.

unpermissioned_feeds_enabled: bool

Enabling this setting means data feeds do not need explicit permission to join the queue and request new values from its oracles.

unpermissioned_vrf_enabled: bool

Enabling this setting means VRF accounts do not need explicit permission to join the queue and request new values from its oracles.

curator_reward_cut: SwitchboardDecimal

TODO: Revenue percentage rewarded to job curators overall.

lock_lease_funding: bool

Prevent new leases from being funded n this queue. Useful to turn down a queue for migrations, since authority is always immutable.

mint: Pubkey

Token mint used for the oracle queue rewards and slashing.

enable_buffer_relayers: bool

Whether oracles are permitted to fulfill buffer relayer update request.

_ebuf: [u8; 968]

Reserved for future info.

max_size: u32

Maximum number of oracles a queue can support.

data_buffer: Pubkey

The public key of the OracleQueueBuffer account holding a collection of Oracle pubkeys that haver successfully heartbeated before the queues oracleTimeout.

Implementations

impl OracleQueueAccountData

pub fn size() -> usize

pub fn convert_buffer(buf: &mut [u8]) -> &mut [Pubkey]

pub fn len(&self) -> u32

pub fn is_empty(&self) -> bool

pub fn get_mint(&self) -> Pubkey

pub fn max_round_rewards(&self, batch_size: u32) -> u64

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

Returns the deserialized Switchboard OracleQueue account

Arguments

• account_info - A Solana AccountInfo referencing an existing Switchboard OracleQueue

Examples

use switchboard_solana::OracleQueueAccountData;

let oracle_queue = OracleQueueAccountData::new(queue_account_info)?;

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

Returns the deserialized Switchboard OracleQueue account

Arguments

• data - A Solana AccountInfo’s data buffer

Examples

use switchboard_solana::OracleQueueAccountData;

let oracle_queue = OracleQueueAccountData::new(oracle_account_info.try_borrow_data()?)?;

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

Available on non-target_os="solana" only.

Trait Implementations

impl AccountDeserialize for OracleQueueAccountData

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 OracleQueueAccountData

fn clone(&self) -> OracleQueueAccountData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for OracleQueueAccountData

fn default() -> Self

Returns the “default value” for a type.

impl Discriminator for OracleQueueAccountData

const DISCRIMINATOR: [u8; 8] = _

fn discriminator() -> [u8; 8]

impl Owner for OracleQueueAccountData

fn owner() -> Pubkey

impl Zeroable for OracleQueueAccountData

fn zeroed() -> Self

Calls zeroed.

impl Copy for OracleQueueAccountData

impl Pod for OracleQueueAccountData
