Enum diem_types::transaction::authenticator::TransactionAuthenticator

pub enum TransactionAuthenticator {
    Ed25519 {
        public_key: Validatable<Ed25519PublicKey>,
        signature: Ed25519Signature,
    },
    MultiEd25519 {
        public_key: MultiEd25519PublicKey,
        signature: MultiEd25519Signature,

        secondary_signer_addresses: Vec<AccountAddress>,
        secondary_signers: Vec<AccountAuthenticator>,
    },
}

Each transaction submitted to the Diem blockchain contains a TransactionAuthenticator. During transaction execution, the executor will check if every AccountAuthenticator’s signature on the transaction hash is well-formed and whether the sha3 hash of the AccountAuthenticator’s AuthenticationKeyPreimage matches the AuthenticationKey stored under the participating signer’s account address.

Trait Implementations

impl Clone for TransactionAuthenticator

fn clone(&self) -> TransactionAuthenticator

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TransactionAuthenticator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TransactionAuthenticator

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TransactionAuthenticator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for TransactionAuthenticator

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

impl PartialEq<TransactionAuthenticator> for TransactionAuthenticator

fn eq(&self, other: &TransactionAuthenticator) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
