§authority: Pubkey

On-chain account delegated for making account changes.

§queue: Pubkey

The OracleQueueAccountData that is assigned to fulfill VRF update request.

§escrow: Pubkey

Implementations§

source §

impl VrfLiteAccountData

source

pub fn size() -> usize

source

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

Returns the deserialized Switchboard VRF Lite account

§Arguments

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

§Examples

use switchboard_solana::VrfLiteAccountData;

let vrf_lite = VrfLiteAccountData::new(vrf_account_info)?;

source

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

Returns the deserialized Switchboard VRF Lite account

§Arguments

data - A Solana AccountInfo’s data buffer

§Examples

use switchboard_solana::VrfLiteAccountData;

let vrf_lite = VrfLiteAccountData::new(vrf_account_info.try_borrow_data()?)?;

source

pub fn get_current_randomness_round_id(&self) -> u128

Returns the current VRF round ID

source

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::VrfLiteAccountData;

source

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

source

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

source

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

Trait Implementations§

source §

impl AccountDeserialize for VrfLiteAccountData

source §

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.

source §

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.
