👎Deprecated since 0.4.0: See RequestV2

(deprecated: see crate::RequestV2) Request randomness.

Required accounts

• (signer) payer – request and transaction fee payer
• (writable) network_state – VRF on-chain config PDA (see network_state_account_address)
• (writable) (from VRF on-chain config) treasury – either SOL treasury or token treasury (see remaining accounts)
• (writable) request – randomness request PDA (see randomness_account_address)
• system_program - system program account

Remaining accounts

If token fee configuration exists and given treasury equals token treasury, then remaining accounts are required:

• (writable) token_payer – payer token wallet
• token_program_account – necessary to execute the transfer

Space calculation for account creation (request)

• 8 (anchor tag) + 32 (seed) + 64 (combined randomness) + 4 (response array length) + (32 (fulfiller pubkey) + 64 (fulfiller randomness)) * 7 (maximum number of responses)

Trait Implementations

impl<'info> Accounts<'info, RequestBumps> for Request<'info>

where 'info: 'info,

fn try_accounts( __program_id: &Pubkey, __accounts: &mut &'info [AccountInfo<'info>], __ix_data: &[u8], __bumps: &mut RequestBumps, __reallocs: &mut BTreeSet<Pubkey>, ) -> Result<Self>

Returns the validated accounts struct. What constitutes “valid” is program dependent. However, users of these types should never have to worry about account substitution attacks. For example, if a program expects a Mint account from the SPL token program in a particular field, then it should be impossible for this method to return Ok if any other account type is given–from the SPL token program or elsewhere.

impl<'info> AccountsExit<'info> for Request<'info>

where 'info: 'info,

fn exit(&self, program_id: &Pubkey) -> Result<()>

program_id is the currently executing program.

impl<'info> Bumps for Request<'info>

where 'info: 'info,

type Bumps = RequestBumps

Struct to hold account bump seeds.

impl<'info> ToAccountInfos<'info> for Request<'info>

where 'info: 'info,

fn to_account_infos(&self) -> Vec<AccountInfo<'info>>

impl<'info> ToAccountMetas for Request<'info>

fn to_account_metas(&self, is_signer: Option<bool>) -> Vec<AccountMeta>

is_signer is given as an optional override for the signer meta field. This covers the edge case when a program-derived-address needs to relay a transaction from a client to another program but sign the transaction before the relay. The client cannot mark the field as a signer, and so we have to override the is_signer meta field given by the client.
