Enum TxType

#[repr(u8)]
pub enum TxType {
    Legacy = 0,
    Eip2930 = 1,
    Eip1559 = 2,
    Eip4844 = 3,
    Eip7702 = 4,
}

The TxEnvelope enum represents all Ethereum transaction envelope types, /// Its variants correspond to specific allowed transactions:

1. Legacy (pre-EIP2718) TxLegacy
2. EIP2930 (state access lists) TxEip2930
3. EIP1559 TxEip1559
4. EIP4844 TxEip4844Variant

This type is generic over Eip4844 variant to support the following cases:

1. Only-crate::TxEip4844 transaction type, such transaction representation is returned by RPC and stored by nodes internally.
2. Only-crate::TxEip4844WithSidecar transactions which are broadcasted over the network, submitted to RPC and stored in transaction pool.
3. Dynamic TxEip4844Variant transactions to support both of the above cases via a single type.

Ethereum TransactionType flags as specified in EIPs 2718, 1559, 2930, 4844, and 7702.
