Required Methods

fn account(&self) -> AccountId

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

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

Provided Methods

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.

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

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

Optional support for locking the signer.
