Implementations

impl<'info> FunctionRequestInitAndTrigger<'info>

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

pub fn invoke( &self, program: AccountInfo<'info>, bounty: Option<u64>, slots_until_expiration: Option<u64>, max_container_params_len: Option<u32>, container_params: Option<Vec<u8>>, garbage_collection_slot: Option<u64>, valid_after_slot: Option<u64> ) -> ProgramResult

Invokes the instruction.

Arguments

• program: The Switchboard Attestation program AccountInfo.

• max_container_params_len: The maximum length of the vector containing the container parameters.

  • Default: 256 bytes.
  • Example: Some(512).

• container_params: The parameters for the container.

  • Default: Empty vector.
  • Example: Some(request_params.into_bytes()).

• garbage_collection_slot: The slot when the request can be closed by anyone and is considered expired.

  • Default: None, meaning only the authority can close the request.

• bounty: An optional fee to reward oracles for priority processing.

  • Default: 0 lamports.

• slots_until_expiration: An optional specification for the max number of slots the request can be processed in.

  • Default: 2250 slots (roughly 15 minutes at 400 ms/slot).
  • Minimum: 150 slots (approximately 1 minute at 400 ms/slot).

• valid_after_slot: Schedule when the request should be valid for processing.

  • Default: 0 slots, meaning the request is valid immediately for oracles to process.

Returns

• ProgramResult: Indicates the result of the instruction execution.

pub fn invoke_signed( &self, program: AccountInfo<'info>, bounty: Option<u64>, slots_until_expiration: Option<u64>, max_container_params_len: Option<u32>, container_params: Option<Vec<u8>>, garbage_collection_slot: Option<u64>, valid_after_slot: Option<u64>, signer_seeds: &[&[&[u8]]] ) -> ProgramResult

Invokes the instruction using a signed authority.

Arguments

• program: The Switchboard Attestation program AccountInfo.

• max_container_params_len: The maximum length of the vector containing the container parameters.

  • Default: 256 bytes.
  • Example: Some(512).

• container_params: The parameters for the container.

  • Default: Empty vector.
  • Example: Some(request_params.into_bytes()).

• garbage_collection_slot: The slot when the request can be closed by anyone and is considered expired.

  • Default: None, meaning only the authority can close the request.

• bounty: An optional fee to reward oracles for priority processing.

  • Default: 0 lamports.

• slots_until_expiration: An optional specification for the max number of slots the request can be processed in.

  • Default: 2250 slots (roughly 15 minutes at 400 ms/slot).
  • Minimum: 150 slots (approximately 1 minute at 400 ms/slot).

• valid_after_slot: Schedule when the request should be valid for processing.

  • Default: 0 slots, meaning the request is valid immediately for oracles to process.

• signer_seeds: Seeds used for signing.

Returns

• ProgramResult: Indicates the result of the instruction execution.

pub fn build_ix( accounts: &FunctionRequestInitAndTriggerAccounts, params: &FunctionRequestInitAndTriggerParams ) -> Result<Instruction, SbError>

Trait Implementations

impl<'info> Accounts<'info, FunctionRequestInitAndTriggerBumps> for FunctionRequestInitAndTrigger<'info>

where 'info: 'info,

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

where 'info: 'info,

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

program_id is the currently executing program.

impl<'info> Bumps for FunctionRequestInitAndTrigger<'info>

where 'info: 'info,

type Bumps = FunctionRequestInitAndTriggerBumps

Struct to hold account bump seeds.

impl Discriminator for FunctionRequestInitAndTrigger<'_>

const DISCRIMINATOR: [u8; 8] = _

fn discriminator() -> [u8; 8]

impl<'info> ToAccountInfos<'info> for FunctionRequestInitAndTrigger<'info>

where 'info: 'info,

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

impl<'info> ToAccountMetas for FunctionRequestInitAndTrigger<'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.
