Required Methods

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

Provided Methods

fn nonce(&self) -> Option<u32>

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(&mut self, _nonce: u32)

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.

Implementors

impl<P: Pair> Signer for PairSigner<P>where
    MultiSignature: From<<P as Pair>::Signature>,
