EVM configuration

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§chain_id: u64

Chain ID of the EVM. Used in CHAINID opcode and transaction’s chain ID check.

Chain ID is introduced EIP-155.

§tx_chain_id_check: bool

Whether to check the transaction’s chain ID.

If set to false, the transaction’s chain ID check will be skipped.

§spec: SPEC

Specification for EVM represent the hardfork

§limit_contract_code_size: Option<usize>

Contract code size limit override.

If None, the limit will be determined by the SpecId (EIP-170 or EIP-7907) at runtime. If Some, this specific limit will be used regardless of SpecId.

Useful to increase this because of tests.

§limit_contract_initcode_size: Option<usize>

Contract initcode size limit override.

If None, the limit will check if limit_contract_code_size is set. If it is set, it will double it for a limit. If it is not set, the limit will be determined by the SpecId (EIP-170 or EIP-7907) at runtime.

Useful to increase this because of tests.

§disable_nonce_check: bool

Skips the nonce validation against the account’s nonce

§max_blobs_per_tx: Option<u64>

Blob max count. EIP-7840 Add blob schedule to EL config files.

If this config is not set, the check for max blobs will be skipped.

§blob_base_fee_update_fraction: Option<u64>

Blob base fee update fraction. EIP-4844 Blob base fee update fraction.

If this config is not set, the blob base fee update fraction will be set to the default value. See also CfgEnv::blob_base_fee_update_fraction.

Default values for Cancun is primitives::eip4844::BLOB_BASE_FEE_UPDATE_FRACTION_CANCUN and for Prague is primitives::eip4844::BLOB_BASE_FEE_UPDATE_FRACTION_PRAGUE.

§tx_gas_limit_cap: Option<u64>

Configures the gas limit cap for the transaction.

If None, default value defined by spec will be used.

Introduced in Osaka in EIP-7825: Transaction Gas Limit Cap with initials cap of 30M.

§memory_limit: u64

A hard memory limit in bytes beyond which OutOfGasError::Memory cannot be resized.

In cases where the gas limit may be extraordinarily high, it is recommended to set this to a sane value to prevent memory allocation panics.

Defaults to 2^32 - 1 bytes per EIP-1985.

§disable_balance_check: bool

Skip balance checks if true

Adds transaction cost to balance to ensure execution doesn’t fail.

By default, it is set to false.

§disable_block_gas_limit: bool

There are use cases where it’s allowed to provide a gas limit that’s higher than a block’s gas limit.

To that end, you can disable the block gas limit validation.

By default, it is set to false.

§disable_eip3607: bool

EIP-3607 rejects transactions from senders with deployed code

In development, it can be desirable to simulate calls from contracts, which this setting allows.

By default, it is set to false.

§disable_base_fee: bool

Disables base fee checks for EIP-1559 transactions

This is useful for testing method calls with zero gas price.

By default, it is set to false.

§Example

Make text bold using attr():

painted.attr(Attribute::Bold);

Make text bold using using bold().

painted.quirk(Quirk::Wrap);

§

fn whenever(&self, value: Condition) -> Painted<&T>

See the crate level docs for more details.

§Example

Enable styling painted only when both stdout and stderr are TTYs:

use yansi::{Paint, Condition};

painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
