Program global state for processing randomness requests.

Fields

bump: u8

The PDA bump.

authority: Pubkey

The program authority.

mint: Pubkey

The token mint for the program reward.

switchboard_service: Pubkey

The Switchboard Service responsible for responding to randomness requests

wallet: Pubkey

Token wallet used for rewards

cost_per_byte: u64

The cost for each randomness request.

last_updated: i64

The unix timestamp when the cost per byte was last updated.

_ebuf: [u8; 512]

Reserved for future use.

Implementations

impl State

pub fn size() -> usize

Returns the size of the function account data in bytes. Includes the discriminator.

pub fn request_cost(&self, num_bytes: u8, options: &TransactionOptions) -> u64

Trait Implementations

impl AccountDeserialize for State

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 AccountSerialize for State

fn try_serialize<W: Write>(&self, writer: &mut W) -> Result<()>

Serializes the account data into writer.

impl BorshDeserialize for State

where u8: BorshDeserialize, Pubkey: BorshDeserialize, u64: BorshDeserialize, i64: BorshDeserialize, [u8; 512]: BorshDeserialize,

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self, Error>

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

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for State

where u8: BorshSerialize, Pubkey: BorshSerialize, u64: BorshSerialize, i64: BorshSerialize, [u8; 512]: BorshSerialize,

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for State

fn clone(&self) -> State

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for State

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

Formats the value using the given formatter.

impl Discriminator for State

const DISCRIMINATOR: [u8; 8] = _

fn discriminator() -> [u8; 8]

impl Owner for State

fn owner() -> Pubkey

impl Space for State

const INIT_SPACE: usize = 657usize
