Response traits and shared types for Alloy's network abstraction.

The response traits (BlockResponse, HeaderResponse, TransactionResponse, and ReceiptResponse) let generic code inspect network-specific RPC values. BlockTransactions represents full transactions, hashes only, or the omitted transaction field used by uncle responses. Because its JSON representation is untagged, an empty [] deserializes as Full([]) and cannot preserve whether a hashes-only request produced it. Builder capability traits describe optional transaction fields without choosing a concrete network.

use alloy_network_primitives::BlockResponse;
use alloy_primitives::TxHash;

fn transaction_hashes<B: BlockResponse>(block: &B) -> Vec<TxHash> {
    block.transactions().hashes().collect()
}
