This expects rlp(legacy_tx)

impl Debug for TransactionSigned

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Decodable for TransactionSigned

fn decode(buf: &mut &[u8]) -> Result<Self>

This Decodable implementation only supports decoding rlp encoded transactions as it’s used by p2p.

The p2p encoding format always includes an RLP header, although the type RLP header depends on whether or not the transaction is a legacy transaction.

If the transaction is a legacy transaction, it is just encoded as a RLP list: rlp(tx-data).

If the transaction is a typed transaction, it is encoded as a RLP string: rlp(tx-type || rlp(tx-data))

This can be used for decoding all signed transactions in p2p BlockBodies responses.

This cannot be used for decoding EIP-4844 transactions in p2p PooledTransactions, since the EIP-4844 variant of TransactionSigned does not include the blob sidecar.

For a method suitable for decoding pooled transactions, see PooledTransactionsElement.

CAUTION: Due to a quirk in [Header::decode], this method will succeed even if a typed transaction is encoded in this format, and does not start with a RLP header: tx-type || rlp(tx-data).

This is because [Header::decode] does not advance the buffer, and returns a length-1 string header if the first byte is less than 0xf7.

fn typed_decode(ty: u8, buf: &mut &[u8]) -> Eip2718Result<Self>

fn decode_2718(buf: &mut &[u8]) -> Result<Self, Eip2718Error>
