SingleSigner::update_nonce

Refresh self.nonce from the chain. Trait method of SequencedSigner.

Signature

#[async_trait]
impl<S> SequencedSigner for SingleSigner<S, Defined<Nonce>>
where
    S: Secret + Send + Sync,
{
    async fn update_nonce<C>(&mut self, client: &C) -> anyhow::Result<()>
    where
        C: QueryClient,
        anyhow::Error: From<C::Error>;
}

Example

use {
    anyhow::Result,
    dango_sdk::{HttpClient, SingleSigner},
    dango_types::signer::SequencedSigner,
};
 
async fn resync(
    http: &HttpClient,
    signer: &mut SingleSigner<impl dango_sdk::Secret + Send + Sync>,
) -> Result<()> {
    signer.update_nonce(http).await
}

Parameters

client — &C implementing QueryClient.

Returns

() — on success, self.nonce is set to the value returned by query_next_nonce.

Notes

  • Use after a broadcast failure to bring the in-memory nonce back in sync with the chain (sign_transaction increments unconditionally).
  • Use after a process restart that resumed signing with a stale nonce.
