Expand description
Transaction with an [AccessList
] (EIP-2930).
Fields§
§chain_id: ChainId
Added as EIP-pub 155: Simple replay attack protection
nonce: u64
A scalar value equal to the number of transactions sent by the sender; formally Tn.
gas_price: u128
A scalar value equal to the number of Wei to be paid per unit of gas for all computation costs incurred as a result of the execution of this transaction; formally Tp.
As ethereum circulation is around 120mil eth as of 2022 that is around 120000000000000000000000000 wei we are safe to use u128 as its max number is: 340282366920938463463374607431768211455
gas_limit: u128
A scalar value equal to the maximum amount of gas that should be used in executing this transaction. This is paid up-front, before any computation is done and may not be increased later; formally Tg.
to: TxKind
The 160-bit address of the message call’s recipient or, for a contract creation transaction, ∅, used here to denote the only member of B0 ; formally Tt.
value: U256
A scalar value equal to the number of Wei to be transferred to the message call’s recipient or, in the case of contract creation, as an endowment to the newly created account; formally Tv.
access_list: AccessList
The accessList specifies a list of addresses and storage keys;
these addresses and storage keys are added into the accessed_addresses
and accessed_storage_keys
global sets (introduced in EIP-2929).
A gas cost is charged, though at a discount relative to the cost of
accessing outside the list.
input: Bytes
Input has two uses depending if transaction is Create or Call (if to
field is None or
Some). pub init: An unlimited size byte array specifying the
EVM-code for the account initialisation procedure CREATE,
data: An unlimited size byte array specifying the
input data of the message call, formally Td.
Implementations§
source§impl TxEip2930
impl TxEip2930
sourcepub fn size(&self) -> usize
pub fn size(&self) -> usize
Calculates a heuristic for the in-memory size of the TxEip2930 transaction.
sourcepub(crate) fn decode_fields(buf: &mut &[u8]) -> Result<Self>
pub(crate) fn decode_fields(buf: &mut &[u8]) -> Result<Self>
Decodes the inner TxEip2930 fields from RLP bytes.
NOTE: This assumes a RLP header has already been decoded, and just decodes the following RLP fields in the following order:
chain_id
nonce
gas_price
gas_limit
to
value
data
(input
)access_list
sourcepub(crate) fn encode_fields(&self, out: &mut dyn BufMut)
pub(crate) fn encode_fields(&self, out: &mut dyn BufMut)
Encodes only the transaction’s fields into the desired buffer, without a RLP header.
sourcepub(crate) fn encoded_len_with_signature(
&self,
signature: &Signature,
with_header: bool,
) -> usize
pub(crate) fn encoded_len_with_signature( &self, signature: &Signature, with_header: bool, ) -> usize
Returns what the encoded length should be, if the transaction were RLP encoded with the
given signature, depending on the value of with_header
.
If with_header
is true
, the payload length will include the RLP header length.
If with_header
is false
, the payload length will not include the RLP header length.
sourcepub(crate) fn encode_with_signature_fields(
&self,
signature: &Signature,
out: &mut dyn BufMut,
)
pub(crate) fn encode_with_signature_fields( &self, signature: &Signature, out: &mut dyn BufMut, )
Encodes the transaction from RLP bytes, including the signature. This does not encode a tx type byte or string header.
This does encode a list header and include a signature.
