#[repr(C)]
pub struct ExtraAccountMeta { pub discriminator: u8, pub address_config: [u8; 32], pub is_signer: PodBool, pub is_writable: PodBool, }
Expand description

Pod type for defining a required account in a validation account.

This can either be a standard AccountMeta or a PDA. Can be used in TLV-encoded data.

Fields§

§discriminator: u8

Discriminator to tell whether this represents a standard AccountMeta or a PDA

§address_config: [u8; 32]

This address_config field can either be the pubkey of the account or the seeds used to derive the pubkey from provided inputs

§is_signer: PodBool

Whether the account should sign

§is_writable: PodBool

Whether the account should be writable

Implementations§

source§

impl ExtraAccountMeta

source

pub fn new_with_pubkey( pubkey: &Pubkey, is_signer: bool, is_writable: bool ) -> Result<Self, ProgramError>

Create a ExtraAccountMeta from a public key, thus representing a standard AccountMeta

source

pub fn new_with_seeds( seeds: &[Seed], is_signer: bool, is_writable: bool ) -> Result<Self, ProgramError>

Create a ExtraAccountMeta from a list of seed configurations, thus representing a PDA

source

pub fn new_external_pda_with_seeds( program_index: u8, seeds: &[Seed], is_signer: bool, is_writable: bool ) -> Result<Self, ProgramError>

Create a ExtraAccountMeta from a list of seed configurations, representing a PDA for an external program

This PDA belongs to a program elsewhere in the account list, rather than the executing program. For a PDA on the executing program, use ExtraAccountMeta::new_with_seeds.

source

pub fn resolve<'a, F>( &self, instruction_data: &[u8], program_id: &Pubkey, get_account_key_data_fn: F ) -> Result<AccountMeta, ProgramError>
where F: Fn(usize) -> Option<(&'a Pubkey, Option<&'a [u8]>)>,

Resolve an ExtraAccountMeta into an AccountMeta, potentially resolving a program-derived address (PDA) if necessary
