The OracleQueueAccountData that is assigned to fulfill VRF update request.

escrow: Pubkey

The token account used to hold funds for VRF update request.

callback: CallbackZC

The callback that is invoked when an update request is successfully verified.

batch_size: u32

The number of oracles assigned to a VRF update request.

builders: [VrfBuilder; 8]

Struct containing the intermediate state between VRF crank actions.

builders_len: u32

Reserved for future info.

Implementations

impl VrfAccountData

pub fn size() -> usize

pub fn new<'info>( switchboard_vrf: &'info AccountInfo<'_> ) -> Result<Ref<'info, VrfAccountData>>

Returns the deserialized Switchboard VRF account

Arguments

• switchboard_vrf - A Solana AccountInfo referencing an existing Switchboard VRF account

Examples

use switchboard_solana::VrfAccountData;

let vrf = VrfAccountData::new(vrf_account_info)?;

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

Returns the deserialized Switchboard VRF account

Arguments

• data - A Solana AccountInfo’s data buffer

Examples

use switchboard_solana::VrfAccountData;

let vrf = VrfAccountData::new(vrf_account_info.try_borrow_data()?)?;

pub fn get_current_randomness_round_id(&self) -> u128

Returns the current VRF round ID

pub fn get_result(&self) -> Result<[u8; 32]>

If sufficient oracle responses, returns the latest on-chain result in SwitchboardDecimal format

Examples

use switchboard_solana::VrfAccountData;

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

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

pub fn fetch_sync<T: SyncClient>( client: &T, pubkey: Pubkey ) -> Result<Self, SbError>

Trait Implementations

impl AccountDeserialize for VrfAccountData

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 VrfAccountData

fn clone(&self) -> VrfAccountData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for VrfAccountData

fn default() -> Self

Returns the “default value” for a type.

impl Discriminator for VrfAccountData

const DISCRIMINATOR: [u8; 8] = _

fn discriminator() -> [u8; 8]

impl Owner for VrfAccountData

fn owner() -> Pubkey

impl Zeroable for VrfAccountData

fn zeroed() -> Self

Calls zeroed.

impl Copy for VrfAccountData

impl Pod for VrfAccountData

impl ZeroCopy for VrfAccountData
