Struct IsWallet

pub struct IsWallet<'a> {
    pub field: &'a Str32,
}

Constraint that represents a test on whether a pubkey can be signed from a client and therefore is a true wallet account or not.

The details of this constraint are as follows: a wallet is defined as being both owned by the System Program and the address is on-curve. The field value in the rule is used to locate the Pubkey in the payload that must be on-curve and for which the owner must be the System Program. 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

field: &'a Str32

The field in the Payload to be checked.

Implementations

impl<'a> IsWallet<'a>

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

Deserialize a constraint from a byte array.

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

Serialize a constraint into a byte array.

Trait Implementations

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