Struct mpl_token_auth_rules::state::ProgramOwned

pub struct ProgramOwned<'a> {
    pub program: &'a Pubkey,
    pub field: &'a Str32,
}

Constraint representing a test where a Pubkey must be owned by a given program.

This constraint requires a PayloadType value of PayloadType::Pubkey. The field value in the rule is used to locate the Pubkey in the payload for which the owner must be the program in the rule. Note this same Pubkey account must also be provided to Validate via the additional_rule_accounts argument. This is so that the Pubkey’s owner can be found from its AccountInfo struct.

Fields

program: &'a Pubkey

The program that must own the Pubkey.

field: &'a Str32

The field in the Payload to be compared.

Implementations

impl<'a> ProgramOwned<'a>

pub fn from_bytes(bytes: &'a [u8]) -> Result<Self, RuleSetError>

Deserialize a constraint from a byte array.

pub fn serialize( field: String, program: Pubkey ) -> Result<Vec<u8>, RuleSetError>

Serialize a constraint into a byte array.

Trait Implementations

impl<'a> Constraint<'a> for ProgramOwned<'a>

fn constraint_type(&self) -> ConstraintType

Returns the type of the constraint.

fn validate( &self, accounts: &HashMap<Pubkey, &AccountInfo<'_>>, payload: &Payload, _update_rule_state: bool, _rule_set_state_pda: &Option<&AccountInfo<'_>>, _rule_authority: &Option<&AccountInfo<'_>> ) -> RuleResult

Validates the constraint condition.
