Bundle of transactions for eth_sendBundle

Note: this is for eth_sendBundle and not mev_sendBundle

https://docs.flashbots.net/flashbots-auction/searchers/advanced/rpc-endpoint#eth_sendbundle

Fields

txs: Vec<Bytes>

A list of hex-encoded signed transactions

block_number: u64

hex-encoded block number for which this bundle is valid

min_timestamp: Option<u64>

unix timestamp when this bundle becomes active

max_timestamp: Option<u64>

unix timestamp how long this bundle stays valid

reverting_tx_hashes: Vec<B256>

list of hashes of possibly reverting txs

replacement_uuid: Option<String>

UUID that can be used to cancel/replace this bundle

Implementations

impl EthSendBundle

pub fn bundle_hash(&self) -> B256

Returns the bundle hash.

This is the keccak256 hash of the transaction hashes of the transactions in the bundle.

Note

Logic for calculating the bundle hash is as follows:

• Calculate the hash of each transaction in the bundle
• Concatenate the hashes, in bundle order
• Calculate the keccak256 hash of the concatenated hashes

See the flashbots impl.

This function will not verify transaction correctness. If the bundle txs contains invalid transactions, the bundle hash will still be calculated.

Trait Implementations

impl Clone for EthSendBundle

fn clone(&self) -> EthSendBundle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EthSendBundle

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

Formats the value using the given formatter.

impl Default for EthSendBundle

fn default() -> EthSendBundle

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EthSendBundle

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EthSendBundle

fn eq(&self, other: &EthSendBundle) -> 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 EthSendBundle

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
