Struct DelegateAction 

pub struct DelegateAction {
    pub sender_id: AccountId,
    pub receiver_id: AccountId,
    pub actions: Vec<NonDelegateAction>,
    pub nonce: u64,
    pub max_block_height: u64,
    pub public_key: PublicKey,
}

Delegate action for meta-transactions.

Fields

sender_id: AccountId

Sender of the delegate action.

receiver_id: AccountId

Receiver of the delegate action.

actions: Vec<NonDelegateAction>

Actions to delegate.

nonce: u64

Nonce for replay protection.

max_block_height: u64

Maximum block height for the action.

public_key: PublicKey

Public key authorizing the delegate.

Implementations

impl DelegateAction

pub fn serialize_for_signing(&self) -> Vec<u8>

Serialize the delegate action for signing.

Per NEP-461, this prepends a u32 prefix (2^30 + 366) before the delegate action, ensuring signed delegate actions are never identical to signed transactions.

Example

let bytes = delegate_action.serialize_for_signing();
let hash = CryptoHash::hash(&bytes);
let signature = signer.sign(hash.as_bytes()).await?;

pub fn get_hash(&self) -> CryptoHash

Get the hash of this delegate action (for signing).

pub fn sign(self, signature: Signature) -> SignedDelegateAction

Sign this delegate action and return a SignedDelegateAction.

Trait Implementations

impl BorshDeserialize for DelegateAction

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for DelegateAction

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for DelegateAction

fn clone(&self) -> DelegateAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DelegateAction

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

Formats the value using the given formatter.

impl PartialEq for DelegateAction

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

Tests for self and other values to be equal, and is used by ==.

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

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