Struct ExecConfig 

pub struct ExecConfig<T: Config> {
    pub bump_nonce: bool,
    pub collect_deposit_from_hold: Option<(u32, Weight)>,
    pub effective_gas_price: Option<U256>,
    pub is_dry_run: Option<DryRunConfig<<<T as Config>::Time as Time>::Moment>>,
    pub mock_handler: Option<Box<dyn MockHandler<T>>>,
}

Stack wide configuration options.

Fields

bump_nonce: bool

Indicates whether the account nonce should be incremented after instantiating a new contract.

In Substrate, where transactions can be batched, the account’s nonce should be incremented after each instantiation, ensuring that each instantiation uses a unique nonce.

For transactions sent from Ethereum wallets, which cannot be batched, the nonce should only be incremented once. In these cases, set this to false to suppress an extra nonce increment.

Note: The origin’s nonce is already incremented pre-dispatch by the CheckNonce transaction extension.

This does not apply to contract initiated instantatiations. Those will always bump the instantiating contract’s nonce.

collect_deposit_from_hold: Option<(u32, Weight)>

Whether deposits will be withdrawn from the pallet_transaction_payment credit (Some) free balance (None).

Contains the encoded_len + base weight.

effective_gas_price: Option<U256>

The gas price that was chosen for this transaction.

It is determined when transforming eth_transact into a proper extrinsic.

is_dry_run: Option<DryRunConfig<<<T as Config>::Time as Time>::Moment>>

Whether this configuration was created for a dry-run execution. Use to enable logic that should only run in dry-run mode.

mock_handler: Option<Box<dyn MockHandler<T>>>

An optional mock handler that can be used to override certain behaviors. This is primarily used for testing purposes and should be None in production environments.

Implementations

impl<T: Config> ExecConfig<T>

pub fn new_substrate_tx() -> Self

Create a default config appropriate when the call originated from a substrate tx.

pub fn new_substrate_tx_without_bump() -> Self

pub fn new_eth_tx( effective_gas_price: U256, encoded_len: u32, base_weight: Weight, ) -> Self

Create a default config appropriate when the call originated from a ethereum tx.

pub fn with_dry_run( self, dry_run_config: DryRunConfig<<<T as Config>::Time as Time>::Moment>, ) -> Self

Set this config to be a dry-run.
