Struct AccountSigner

pub struct AccountSigner { /* private fields */ }

AccountSigner is wrapper for signing keys (sr25519, ed25519, etc…).

Implementations

impl AccountSigner

pub fn new<P: KeypairSigner + 'static>(pair: P) -> Self

pub fn from_string(s: &str) -> Result<Self, Error>

Generate signing key pair from string s.

Trait Implementations

impl Clone for AccountSigner

fn clone(&self) -> AccountSigner

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<Keyring> for AccountSigner

fn from(key: Keyring) -> Self

Converts to this type from the input type.

impl From<Keyring> for AccountSigner

fn from(key: Keyring) -> Self

Converts to this type from the input type.

impl Signer for AccountSigner

fn account(&self) -> AccountId

fn sign<'life0, 'life1, 'async_trait>( &'life0 self, msg: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = Result<MultiSignature>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn lock<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Option<Box<dyn Signer>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Optional support for locking the signer.

fn nonce<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Option<u32>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Optional - The signer can manage their nonce for improve transaction performance. The default implmentation will query the next nonce from chain storage.

fn set_nonce<'life0, 'async_trait>( &'life0 mut self, _nonce: u32, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Optional - The signer can manage their nonce for improve transaction performance. If the transaction is accepted by the RPC node, then the nonce we be increased, to allow the next transaction to be signed & submitted without waiting for the next block.
