Struct TransactionConditional

pub struct TransactionConditional {
    pub known_accounts: AddressHashMap<AccountStorage>,
    pub block_number_min: Option<BlockNumber>,
    pub block_number_max: Option<BlockNumber>,
    pub timestamp_min: Option<u64>,
    pub timestamp_max: Option<u64>,
}

Options for conditional raw transaction submissions.

TransactionConditional represents the preconditions that determine the inclusion of the transaction, enforced out-of-protocol by the sequencer.

Fields

known_accounts: AddressHashMap<AccountStorage>

A map of account addresses to their expected storage states. Each account can have a specified storage root or explicit slot-value pairs.

block_number_min: Option<BlockNumber>

The minimal block number at which the transaction can be included. None indicates no minimum block number constraint.

block_number_max: Option<BlockNumber>

The maximal block number at which the transaction can be included. None indicates no maximum block number constraint.

timestamp_min: Option<u64>

The minimal timestamp at which the transaction can be included. None indicates no minimum timestamp constraint.

timestamp_max: Option<u64>

The maximal timestamp at which the transaction can be included. None indicates no maximum timestamp constraint.

Implementations

impl TransactionConditional

pub const fn has_exceeded_block_attributes( &self, block: &BlockConditionalAttributes, ) -> bool

Returns true if any configured block parameter (timestamp_max, block_number_max) are exceeded by the given block parameter.

E.g. the block parameter’s timestamp is higher than the configured block_number_max

pub const fn has_exceeded_block_number(&self, block_number: BlockNumber) -> bool

Returns true if the configured max block number is lower or equal to the given block_number

pub const fn has_exceeded_timestamp(&self, timestamp: u64) -> bool

Returns true if the configured max timestamp is lower or equal to the given timestamp

pub const fn matches_block_attributes( &self, block: &BlockConditionalAttributes, ) -> bool

Returns true if the transaction matches the given block attributes.

pub const fn matches_block_number(&self, block_number: BlockNumber) -> bool

Returns true if the transaction matches the given block number.

pub const fn matches_timestamp(&self, timestamp: u64) -> bool

Returns true if the transaction matches the given timestamp.

pub fn cost(&self) -> u64

Computes the aggregate cost of the preconditions; total number of storage lookups required

Trait Implementations

impl Clone for TransactionConditional

fn clone(&self) -> TransactionConditional

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionConditional

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

Formats the value using the given formatter.

impl Default for TransactionConditional

fn default() -> TransactionConditional

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TransactionConditional

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TransactionConditional

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
