Struct PubkeyTreeMatch

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

Constraing representing a test where a Pubkey must be 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. The Pubkey and the proof are 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 Pubkey.

proof_field: &'a Str32

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

root: &'a [u8; 32]

The root of the Merkle tree.

Implementations

impl<'a> PubkeyTreeMatch<'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 PubkeyTreeMatch<'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.
