Enum AccountState

pub enum AccountState {
    NotExisting,
    Touched,
    StorageCleared,
    None,
}

Variants§

§

NotExisting

Before Spurious Dragon hardfork there was a difference between empty and not existing. And we are flagging it here.

§

Touched

EVM touched this account. For newer hardfork this means it can be cleared/removed from state.

§

StorageCleared

EVM cleared storage of this account, mostly by selfdestruct, we don’t ask database for storage slots and assume they are U256::ZERO

§

None

EVM didn’t interacted with this account

Implementations§

§

impl AccountState

pub fn is_storage_cleared(&self) -> bool

Returns true if EVM cleared storage of this account
