Struct CfgEnv

#[non_exhaustive]
pub struct CfgEnv {
    pub chain_id: u64,
    pub kzg_settings: EnvKzgSettings,
    pub perf_analyse_created_bytecodes: AnalysisKind,
    pub limit_contract_code_size: Option<usize>,
    pub disable_nonce_check: bool,
}

EVM configuration.

Fields (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, it will be compared to the transaction’s Chain ID. Chain ID is introduced EIP-155

kzg_settings: EnvKzgSettings

KZG Settings for point evaluation precompile. By default, this is loaded from the ethereum mainnet trusted setup.

perf_analyse_created_bytecodes: AnalysisKind

Bytecode that is created with CREATE/CREATE2 is by default analysed and jumptable is created. This is very beneficial for testing and speeds up execution of that bytecode if called multiple times.

Default: Analyse

limit_contract_code_size: Option<usize>

If some it will effects EIP-170: Contract code size limit. Useful to increase this because of tests. By default it is 0x6000 (~25kb).

disable_nonce_check: bool

Skips the nonce validation against the account’s nonce.

Implementations

impl CfgEnv

pub fn max_code_size(&self) -> usize

Returns max code size from Self::limit_contract_code_size if set or default [MAX_CODE_SIZE] value.

pub fn with_chain_id(self, chain_id: u64) -> Self

pub fn is_eip3607_disabled(&self) -> bool

pub fn is_balance_check_disabled(&self) -> bool

pub fn is_gas_refund_disabled(&self) -> bool

pub fn is_base_fee_check_disabled(&self) -> bool

pub fn is_block_gas_limit_disabled(&self) -> bool

pub const fn is_nonce_check_disabled(&self) -> bool

Trait Implementations

impl Clone for CfgEnv

fn clone(&self) -> CfgEnv

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CfgEnv

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

Formats the value using the given formatter.

impl Default for CfgEnv

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CfgEnv

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CfgEnv

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for CfgEnv

impl StructuralPartialEq for CfgEnv
