Struct spl_tlv_account_resolution::account::ExtraAccountMeta

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

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

impl ExtraAccountMeta

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

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

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.

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

Trait Implementations

impl Clone for ExtraAccountMeta

fn clone(&self) -> ExtraAccountMeta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExtraAccountMeta

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

Formats the value using the given formatter.

impl Default for ExtraAccountMeta

fn default() -> ExtraAccountMeta

Returns the “default value” for a type.

impl From<&AccountInfo<'_>> for ExtraAccountMeta

fn from(account_info: &AccountInfo<'_>) -> Self

Converts to this type from the input type.

impl From<&AccountMeta> for ExtraAccountMeta

fn from(meta: &AccountMeta) -> Self

Converts to this type from the input type.

impl From<AccountInfo<'_>> for ExtraAccountMeta

fn from(account_info: AccountInfo<'_>) -> Self

Converts to this type from the input type.

impl From<AccountMeta> for ExtraAccountMeta

fn from(meta: AccountMeta) -> Self

Converts to this type from the input type.

impl PartialEq for ExtraAccountMeta

fn eq(&self, other: &ExtraAccountMeta) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&ExtraAccountMeta> for AccountMeta

type Error = ProgramError

The type returned in the event of a conversion error.

fn try_from(pod: &ExtraAccountMeta) -> Result<Self, Self::Error>

Performs the conversion.

impl Zeroable for ExtraAccountMeta

fn zeroed() -> Self

Calls zeroed.

impl Copy for ExtraAccountMeta

impl Pod for ExtraAccountMeta

impl StructuralPartialEq for ExtraAccountMeta
