Struct AdditionalSigner 

pub struct AdditionalSigner<'a> {
    pub account: &'a Pubkey,
}

Constraint representing the requirement that An additional signer must be present.

This constraint does not require any Payload values, but the additional signer account must be provided to Validate via the additional_rule_accounts argument so that whether it is a signer can be retrieved from its AccountInfo struct.

Fields

account: &'a Pubkey

The public key that must have also signed the transaction.

Implementations

impl<'a> AdditionalSigner<'a>

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

Deserialize a constraint from a byte array.

pub fn serialize(account: Pubkey) -> Result<Vec<u8>, RuleSetError>

Serialize a constraint into a byte array.

Trait Implementations

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