pub async fn codehash_at<P: Provider>(
provider: &P,
address: Address,
) -> Result<B256>Expand description
The code hash of the account at address, as EXTCODEHASH reports it
for an account with code: keccak256 of its runtime bytecode. An
account without code is an error rather than keccak256("") or zero,
because setTrustRoots refuses both and a caller comparing against the
hash of nothing has nothing to pin.
