The transaction environment.

Fields

caller: Address

Caller aka Author aka transaction signer.

gas_limit: u64

The gas limit of the transaction.

gas_price: Uint<256, 4>

The gas price of the transaction.

transact_to: TxKind

The destination of the transaction.

value: Uint<256, 4>

The value sent to transact_to.

data: Bytes

The data of the transaction.

nonce: Option<u64>

The nonce of the transaction.

Caution: If set to None, then nonce validation against the account’s nonce is skipped: InvalidTransaction::NonceTooHigh and InvalidTransaction::NonceTooLow

chain_id: Option<u64>

The chain ID of the transaction. If set to None, no checks are performed.

Incorporated as part of the Spurious Dragon upgrade via EIP-155.

access_list: Vec<AccessListItem>

A list of addresses and storage keys that the transaction plans to access.

Added in EIP-2930.

gas_priority_fee: Option<Uint<256, 4>>

The priority fee per gas.

Incorporated as part of the London upgrade via EIP-1559.

blob_hashes: Vec<FixedBytes<32>>

The list of blob versioned hashes. Per EIP there should be at least one blob present if Self::max_fee_per_blob_gas is Some.

Incorporated as part of the Cancun upgrade via EIP-4844.

max_fee_per_blob_gas: Option<Uint<256, 4>>

The max fee per blob gas.

Incorporated as part of the Cancun upgrade via EIP-4844.

authorization_list: Option<AuthorizationList>

List of authorizations, that contains the signature that authorizes this caller to place the code to signer account.

Set EOA account code for one transaction

EIP-Set EOA account code for one transaction

optimism: OptimismFields

Available on crate feature optimism only.

Optimism fields.

Implementations

impl TxEnv

pub fn get_total_blob_gas(&self) -> u64

See EIP-4844, Env::calc_data_fee, and Env::calc_max_data_fee.

pub fn clear(&mut self)

Clears environment and resets fields to default values.

Trait Implementations

impl Clone for TxEnv

fn clone(&self) -> TxEnv

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TxEnv

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

Formats the value using the given formatter.

impl Default for TxEnv

fn default() -> TxEnv

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TxEnv

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TxEnv

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

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 TxEnv

impl StructuralPartialEq for TxEnv

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
