Additional TxEnv fields for optimism.

Fields

source_hash: Option<FixedBytes<32>>

The source hash is used to make sure that deposit transactions do not have identical hashes.

L1 originated deposit transaction source hashes are computed using the hash of the l1 block hash and the l1 log index. L1 attributes deposit source hashes are computed with the l1 block hash and the sequence number = l2 block number - l2 epoch start block number.

These two deposit transaction sources specify a domain in the outer hash so there are no collisions.

mint: Option<u128>

The amount to increase the balance of the from account as part of a deposit transaction. This is unconditional and is applied to the from account even if the deposit transaction fails since the deposit is pre-paid on L1.

is_system_transaction: Option<bool>

Whether or not the transaction is a system transaction.

enveloped_tx: Option<Bytes>

An enveloped EIP-2718 typed transaction. This is used to compute the L1 tx cost using the L1 block info, as opposed to requiring downstream apps to compute the cost externally. This field is optional to allow the TxEnv to be constructed for non-optimism chains when the optimism feature is enabled, but the CfgEnv optimism field is set to false.

Trait Implementations

impl Clone for OptimismFields

fn clone(&self) -> OptimismFields

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OptimismFields

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

Formats the value using the given formatter.

impl Default for OptimismFields

fn default() -> OptimismFields

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OptimismFields

fn deserialize<__D>( __deserializer: __D ) -> Result<OptimismFields, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for OptimismFields

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for OptimismFields

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for OptimismFields

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for OptimismFields

impl StructuralPartialEq for OptimismFields
