Runtime base backend. The immutable and limited part of RuntimeBackend.

Required Methods

fn balance(&self, address: H160) -> U256

Get balance of address.

fn code(&self, address: H160) -> Vec<u8>

Get code of address.

fn storage(&self, address: H160, index: H256) -> H256

Get storage value of address at index.

fn transient_storage(&self, address: H160, index: H256) -> H256

Get transient storage value of address at index.

fn exists(&self, address: H160) -> bool

Check whether an address exists.

If you are running Rust EVM on Ethereum mainnet, set the Backend to pre-EIP161 rule, and the Overlay with config for post-EIP161 rule.

fn nonce(&self, address: H160) -> U256

Get the current nonce of an account.

Provided Methods

fn code_size(&self, address: H160) -> U256

Get code size of address.

fn code_hash(&self, address: H160) -> H256

Get code hash of address.

The caller is responsible for checking whether the account is empty.

fn can_create(&self, address: H160) -> bool

Detect for create collision. Note EIP-7610.
