Implementations

impl<'info> VrfRequestRandomness<'info>

pub fn get_instruction( &self, program_id: Pubkey, params: VrfRequestRandomnessParams ) -> Result<Instruction>

pub fn invoke( &self, program: AccountInfo<'info>, state_bump: u8, permission_bump: u8 ) -> ProgramResult

pub fn invoke_signed( &self, program: AccountInfo<'info>, state_bump: u8, permission_bump: u8, signer_seeds: &[&[&[u8]]] ) -> ProgramResult

Trait Implementations

impl<'info> Accounts<'info, VrfRequestRandomnessBumps> for VrfRequestRandomness<'info>

where 'info: 'info,

fn try_accounts( __program_id: &Pubkey, __accounts: &mut &'info [AccountInfo<'info>], __ix_data: &[u8], __bumps: &mut VrfRequestRandomnessBumps, __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 VrfRequestRandomness<'info>

where 'info: 'info,

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

program_id is the currently executing program.

impl<'info> Bumps for VrfRequestRandomness<'info>

where 'info: 'info,

type Bumps = VrfRequestRandomnessBumps

Struct to hold account bump seeds.

impl Discriminator for VrfRequestRandomness<'_>

const DISCRIMINATOR: [u8; 8] = _

fn discriminator() -> [u8; 8]

impl<'info> ToAccountInfos<'info> for VrfRequestRandomness<'info>

where 'info: 'info,

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

impl<'info> ToAccountMetas for VrfRequestRandomness<'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.
