Struct EnvironmentBuilder 

pub struct EnvironmentBuilder { /* private fields */ }

A builder for creating an Environment.

This builder allows for the configuration of an Environment before it is instantiated. It provides methods for setting the label, gas limit, contract size limit, and a database for the Environment.

Implementations

impl EnvironmentBuilder

pub fn build(self) -> Environment

Builds and runs an Environment with the parameters set in the EnvironmentBuilder.

pub fn with_label(self, label: impl Into<String>) -> Self

Sets the label for the Environment.

pub fn with_gas_limit(self, gas_limit: U256) -> Self

Sets the gas limit for the Environment.

pub fn with_contract_size_limit(self, contract_size_limit: usize) -> Self

Sets the contract size limit for the Environment.

pub fn with_state(self, state: impl Into<CacheDB<EmptyDB>>) -> Self

Sets the state for the Environment. This can come from a saved state of a simulation or a database::fork::Fork.

pub fn with_logs(self, logs: impl Into<HashMap<U256, Vec<eLog>>>) -> Self

Sets the logs for the Environment. This can come from a saved state of a simulation and can be useful for doing analysis.

pub fn with_arbiter_db(self, db: ArbiterDB) -> Self

Sets the entire database for the Environment including both the state and logs. This can come from the saved state of a simulation and can be useful for doing analysis.

pub fn with_console_logs(self) -> Self

Enables inner contract logs to be printed to the console as trace level logs prepended with “Console logs: “.

pub fn with_pay_gas(self) -> Self

Turns on gas payments for transactions so that the [EVM] will automatically pay for gas and revert if balance is not met by sender.
