Configures the executor environment during tests.

Fields

code_size_limit: Option<usize>

EIP-170: Contract code size limit in bytes. Useful to increase this because of tests. By default, it is 0x6000 (~25kb).

chain: Option<Chain>

The chain name or EIP-155 chain ID.

gas_price: Option<u64>

The gas price.

block_base_fee_per_gas: Option<u64>

The base fee in a block.

tx_origin: Option<Address>

The transaction origin.

block_coinbase: Option<Address>

The coinbase of the block.

block_timestamp: Option<u64>

The timestamp of the block.

block_number: Option<u64>

The block number.

block_difficulty: Option<u64>

The block difficulty.

block_prevrandao: Option<B256>

The block prevrandao value. NOTE: Before merge this field was mix_hash.

block_gas_limit: Option<u64>

The block gas limit.

memory_limit: Option<u64>

The memory limit per EVM execution in bytes. If this limit is exceeded, a MemoryLimitOOG result is thrown.

The default is 128MiB.

disable_block_gas_limit: bool

Whether to disable the block gas limit checks.

Trait Implementations

impl Args for EnvArgs

fn group_id() -> Option<Id>

Report the [ArgGroup::id][crate::ArgGroup::id] for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate Self via [FromArgMatches::from_arg_matches_mut]

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate self via [FromArgMatches::update_from_arg_matches_mut]

impl Clone for EnvArgs

fn clone(&self) -> EnvArgs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CommandFactory for EnvArgs

fn command<'b>() -> Command

Build a [Command] that can instantiate Self.

fn command_for_update<'b>() -> Command

where __S: Serializer,

Serialize this value into the given Serde serializer.

Layout

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.
