Quickstart

...
use substreams_abi::erc20::events::Transfer;

// Iterates over successful transactions
for trx in block.transactions() {
  // Iterates over all logs in the transaction, excluding those from calls that were not recorded to the chain's state.
  // The logs are sorted by their ordinal and returned as pairs of (log, call) where call is the call that produced the log.
  for (log, call_view) in trx.logs_with_calls() {
    // -- Transfer --
    let transfer = match Transfer::decode(&log) {
        Some(transfer) => transfer,
        None => continue,
    };
    // transfer.from => 6D1D1ebe7dA598194293784252659e862d55b52c
    // transfer.to => c7bBeC68d12a0d1830360F8Ec58fA599bA1b0e9b
    // transfer.value => 3400000000
  }
