pub struct CacheState {
    pub accounts: HashMap<Address, CacheAccount>,
    pub contracts: HashMap<B256, Bytecode>,
    pub has_state_clear: bool,
}
Expand description

Cache state contains both modified and original values.

Cache state is main state that revm uses to access state. It loads all accounts from database and applies revm output to it.

It generates transitions that is used to build BundleState.

Fields§

§accounts: HashMap<Address, CacheAccount>

Block state account with account state

§contracts: HashMap<B256, Bytecode>

created contracts TODO add bytecode counter for number of bytecodes added/removed.

§has_state_clear: bool

Has EIP-161 state clear enabled (Spurious Dragon hardfork).
