Returns a mutable reference to the environment.

fn load_account_delegated(&mut self, _address: Address) -> Option<AccountLoad>

Load an account code.

fn block_hash(&mut self, _number: u64) -> Option<B256>

Get the block hash of the given block number.

fn balance(&mut self, _address: Address) -> Option<StateLoad<U256>>

Get code hash of address and if the account is cold.

fn sload(&mut self, _address: Address, index: U256) -> Option<StateLoad<U256>>

Get storage value of address at index and if the account is cold.

fn sstore( &mut self, _address: Address, index: U256, value: U256, ) -> Option<StateLoad<SStoreResult>>

Set storage value of account address at index.

fn tload(&mut self, _address: Address, index: U256) -> U256

impl PartialEq for DummyHost

fn eq(&self, other: &DummyHost) -> 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.
