Struct TxLegacy

pub struct TxLegacy {
    pub chain_id: Option<ChainId>,
    pub nonce: u64,
    pub gas_price: u128,
    pub gas_limit: u64,
    pub to: TxKind,
    pub value: U256,
    pub input: Bytes,
}

Legacy transaction.

Fields

chain_id: Option<ChainId>

Added as EIP-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: u64

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.

input: Bytes

Input has two uses depending if to field is Create or Call. 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.

impl IsTyped2718 for TxLegacy

fn is_type(type_id: u8) -> bool

Returns true if the given type ID corresponds to a supported typed transaction.

impl PartialEq for TxLegacy

fn eq(&self, other: &TxLegacy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Outputs the length of the signature RLP encoding for the transaction.

fn set_chain_id_checked(&mut self, chain_id: ChainId) -> bool

fn encoded_for_signing(&self) -> Vec<u8>

RLP-encodes the transaction for signing it. Used to calculate signature_hash.

fn signature_hash(&self) -> B256

Calculate the signing hash for the transaction.

Get gas_limit.

fn gas_price(&self) -> Option<u128>

Get gas_price.

fn max_fee_per_gas(&self) -> u128

For dynamic fee transactions returns the maximum fee per gas the caller is willing to pay.

fn max_priority_fee_per_gas(&self) -> Option<u128>
