Struct revm::db::states::reverts::AccountRevert

pub struct AccountRevert {
    pub account: AccountInfoRevert,
    pub storage: HashMap<U256, RevertToSlot>,
    pub previous_status: AccountStatus,
    pub wipe_storage: bool,
}

Assumption is that Revert can return full state from any future state to any past state.

It is created when new account state is applied to old account state. And it is used to revert new account state to the old account state.

AccountRevert is structured in this way as we need to save it inside database. And we need to be able to read it from database.

Fields

account: AccountInfoRevert

storage: HashMap<U256, RevertToSlot>

previous_status: AccountStatus

wipe_storage: bool

Implementations

impl AccountRevert

pub fn size_hint(&self) -> usize

The approximate size of changes needed to store this account revert. 1 + storage_reverts_len

pub fn new_selfdestructed_again( status: AccountStatus, account: AccountInfoRevert, previous_storage: StorageWithOriginalValues, updated_storage: StorageWithOriginalValues ) -> Self

Very similar to new_selfdestructed but it will add additional zeros (RevertToSlot::Destroyed) for the storage that are set if account is again created.

pub fn new_selfdestructed_from_bundle( account_info_revert: AccountInfoRevert, bundle_account: &mut BundleAccount, updated_storage: &StorageWithOriginalValues ) -> Option<Self>

Create revert for states that were before selfdestruct.

pub fn new_selfdestructed( status: AccountStatus, account: AccountInfoRevert, storage: StorageWithOriginalValues ) -> Self

Create new selfdestruct revert.

pub fn is_empty(&self) -> bool

Returns true if there is nothing to revert, by checking that:

• both account info and storage have been left untouched
• we don’t need to wipe storage

Trait Implementations

impl Clone for AccountRevert

fn clone(&self) -> AccountRevert

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AccountRevert

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AccountRevert

fn default() -> AccountRevert

Returns the “default value” for a type.

impl PartialEq for AccountRevert

fn eq(&self, other: &AccountRevert) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
