pub struct PendingTransaction<'a, P> { /* private fields */ }
Expand description

A pending transaction is a transaction which has been submitted but is not yet mined. await’ing on a pending transaction will resolve to a transaction receipt once the transaction has enough confirmations. The default number of confirmations is 1, but may be adjusted with the confirmations method. If the transaction does not have enough confirmations or is not mined, the future will stay in the pending state.

§Example

use ethers_core::types::TransactionRequest;

let tx = TransactionRequest::new().to(to).value(1000).from(from);
let receipt = client
    .send_transaction(tx, None)
    .await?                           // PendingTransaction<_>
    .log_msg("Pending transfer hash") // print pending tx hash with message
    .await?;                          // Result<Option<TransactionReceipt>, _>
