Struct BundleValidator 

pub struct BundleValidator;

Validator for Flashbots bundles

Implementations

impl BundleValidator

pub fn validate_bundle(bundle: &Bundle) -> FlashbotsResult<()>

Validates a bundle for correctness and Flashbots compatibility

Params

bundle - The bundle to validate

Returns

FlashbotsResult<()> - Ok if valid, Err with validation error otherwise

Example

let bundle = Bundle {
    txs: vec!["0x02f87401843b9aca00843b9aca0082520894...".to_string()],
    block_number: Some(12345678.into()),
    min_timestamp: None,
    max_timestamp: None,
    reverting_tx_hashes: None,
};

match BundleValidator::validate_bundle(&bundle) {
    Ok(()) => println!("Bundle is valid"),
    Err(e) => println!("Bundle validation failed: {}", e),
}

pub fn validate_block_number( current_block: U64, target_block: U64, ) -> FlashbotsResult<()>

Validates that the target block number is in the future and within acceptable range

Params

current_block - The current block number target_block - The target block number for bundle inclusion

Returns

FlashbotsResult<()> - Ok if valid, Err with validation error otherwise

Example

let current_block = U64::from(12345678);
let target_block = U64::from(12345680);

match BundleValidator::validate_block_number(current_block, target_block) {
    Ok(()) => println!("Block number validation passed"),
    Err(e) => println!("Block number validation failed: {}", e),
}

pub fn calculate_bundle_hash(bundle: &Bundle) -> FlashbotsResult<H256>

Calculates the Keccak-256 hash of a serialized bundle

Params

bundle - The bundle to hash

Returns

FlashbotsResult - The bundle hash if successful

Example

let bundle = Bundle {
    txs: vec!["0x02f87401843b9aca00843b9aca0082520894...".to_string()],
    block_number: Some(12345678.into()),
    min_timestamp: None,
    max_timestamp: None,
    reverting_tx_hashes: None,
};

match BundleValidator::calculate_bundle_hash(&bundle) {
    Ok(hash) => println!("Bundle hash: {:?}", hash),
    Err(e) => println!("Failed to calculate bundle hash: {}", e),
}
