Struct PairSigner

pub struct PairSigner<P: KeypairSigner + Clone> {
    pub pair: P,
    pub nonce: u32,
    pub account: AccountId,
}

Fields

pair: P

nonce: u32

account: AccountId

Implementations

impl<P> PairSigner<P>

where P: KeypairSigner,

pub fn new(pair: P) -> Self

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

Generate signing key pair from string s.

Trait Implementations

impl<P: Clone + KeypairSigner + Clone> Clone for PairSigner<P>

fn clone(&self) -> PairSigner<P>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P: KeypairSigner> Signer for PairSigner<P>

fn account(&self) -> AccountId

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

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