Trace object

Fields

from: Option<Address>

The address of the sender who initiated the transaction.

to: Option<Address>

The address of the recipient of the transaction if it was a transaction to an address. For contract creation transactions, this field is None.

call_type: Option<String>

The type of trace, call or delegatecall, two ways to invoke a function in a smart contract.

call creates a new environment for the function to work in, so changes made in that function won’t affect the environment where the function was called.

delegatecall doesn’t create a new environment. Instead, it runs the function within the environment of the caller, so changes made in that function will affect the caller’s environment.

gas: Option<Quantity>

The units of gas included in the transaction by the sender.

input: Option<Data>

The optional input data sent with the transaction, usually used to interact with smart contracts.

init: Option<Data>

The init code.

value: Option<Quantity>

The value of the native token transferred along with the transaction, in Wei.

author: Option<Address>

The address of the receiver for reward transaction.

reward_type: Option<String>

Kind of reward. Block reward or Uncle reward.

block_hash: Option<Hash>

The hash of the block in which the transaction was included.

block_number: Option<u64>

The number of the block in which the transaction was included.

address: Option<Address>

Destroyed address.

code: Option<Data>

Contract code.

gas_used: Option<Quantity>

The total used gas by the call, encoded as hexadecimal.

output: Option<Data>

The return value of the call, encoded as a hexadecimal string.

subtraces: Option<u64>

The number of sub-traces created during execution. When a transaction is executed on the EVM, it may trigger additional sub-executions, such as when a smart contract calls another smart contract or when an external account is accessed.

trace_address: Option<Vec<u64>>

An array that indicates the position of the transaction in the trace.

transaction_hash: Option<Hash>

The hash of the transaction.

transaction_position: Option<u64>

The index of the transaction in the block.

type_: Option<String>

The type of action taken by the transaction, call, create, reward and suicide.

call is the most common type of trace and occurs when a smart contract invokes another contract’s function.

create represents the creation of a new smart contract. This type of trace occurs when a smart contract is deployed to the blockchain.

error: Option<String>

A string that indicates whether the transaction was successful or not.

None if successful, Reverted if not.

sighash: Option<Data>

4-byte function signature hash for the trace

action_address: Option<Address>

The action address for traces that create contracts

balance: Option<Quantity>

The balance associated with the trace operation

refund_address: Option<Address>

The refund address for refund operations

Implementations

impl Trace

pub fn from_arrow(batch: &RecordBatch) -> Result<Vec<Self>>

Convert an arrow RecordBatch into a vector of Trace structs

Trait Implementations

impl Clone for Trace

fn clone(&self) -> Trace

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Trace

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

Formats the value using the given formatter.

impl Default for Trace

fn default() -> Trace

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Trace

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Trace

fn eq(&self, other: &Trace) -> 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.

impl Serialize for Trace

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<TraceReader<'_>> for Trace

type Error = Error

The type returned in the event of a conversion error.

fn try_from(reader: TraceReader<'_>) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Trace

impl StructuralPartialEq for Trace
