Struct mpl_token_auth_rules::state::constraint::ProgramOwnedTree

pub struct ProgramOwnedTree<'a> {
    pub pubkey_field: &'a Str32,
    pub proof_field: &'a Str32,
    pub root: &'a [u8; 32],
}

Constraint representing a test where the Pubkey must be owned by a member of the Merkle tree in the rule.

This constraint requires PayloadType values of PayloadType::Pubkey and PayloadType::MerkleProof. The field values in the Rule are used to locate them in the Payload. 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. The owner and the proof are then used to calculate a Merkle root, which is compared against the root stored in the rule.

Fields

pubkey_field: &'a Str32

The field in the Payload to be compared when looking for the Merkle proof.

proof_field: &'a Str32

The field in the Payload to be compared when looking for the Pubkey.

root: &'a [u8; 32]

The root of the Merkle tree.

Implementations

impl<'a> ProgramOwnedTree<'a>

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

Deserialize a constraint from a byte array.

pub fn serialize( pubkey_field: String, proof_field: String, root: &[u8; 32] ) -> Result<Vec<u8>, RuleSetError>

Serialize a constraint into a byte array.

Trait Implementations

impl<'a> Constraint<'a> for ProgramOwnedTree<'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.
