Struct TransitionAccount
pub struct TransitionAccount {
pub info: Option<AccountInfo>,
pub status: AccountStatus,
pub previous_info: Option<AccountInfo>,
pub previous_status: AccountStatus,
pub storage: HashMap<Uint<256, 4>, StorageSlot, RandomState>,
pub storage_was_destroyed: bool,
}
Expand description
Account Created when EVM state is merged to cache state. And it is sent to Block state.
It is used when block state gets merged to bundle state to create needed Reverts.
Fields§
§info: Option<AccountInfo>
§status: AccountStatus
§previous_info: Option<AccountInfo>
Previous account info is needed for account that got initially loaded. Initially loaded account are not present inside bundle and are needed to generate Reverts.
previous_status: AccountStatus
Mostly needed when previous status Loaded/LoadedEmpty.
storage: HashMap<Uint<256, 4>, StorageSlot, RandomState>
Storage contains both old and new account
storage_was_destroyed: bool
If there is transition that clears the storage we should mark it here and
delete all storages in BundleState. This flag is needed if we have transition
between Destroyed states from DestroyedChanged-> DestroyedAgain-> DestroyedChanged
in the end transition that we would have would be DestroyedChanged->DestroyedChanged
and with only that info we couldn’t decide what to do.
Implementations§
§impl TransitionAccount
impl TransitionAccount
pub fn new_empty_eip161(
storage: HashMap<Uint<256, 4>, StorageSlot, RandomState>,
) -> TransitionAccount
pub fn new_empty_eip161( storage: HashMap<Uint<256, 4>, StorageSlot, RandomState>, ) -> TransitionAccount
Create new LoadedEmpty account.
pub fn has_new_contract(&self) -> Option<(FixedBytes<32>, &Bytecode)>
pub fn has_new_contract(&self) -> Option<(FixedBytes<32>, &Bytecode)>
Return new contract bytecode if it is changed or newly created.
pub fn previous_balance(&self) -> Uint<256, 4>
pub fn previous_balance(&self) -> Uint<256, 4>
Return the balance of account before transition.
pub fn current_balance(&self) -> Uint<256, 4>
pub fn current_balance(&self) -> Uint<256, 4>
Return the balance of account after transition.
pub fn balance_delta(&self) -> Option<Signed<256, 4>>
pub fn balance_delta(&self) -> Option<Signed<256, 4>>
Calculate the change in account’s balance for this transition.
Returns None
if delta does not fit in I256.
pub fn update(&mut self, other: TransitionAccount)
pub fn update(&mut self, other: TransitionAccount)
Update new values of transition. Don’t override old values. Both account info and old storages need to be left intact.
pub fn create_revert(self) -> Option<AccountRevert>
pub fn create_revert(self) -> Option<AccountRevert>
Consume Self and create account revert from it.
pub fn present_bundle_account(&self) -> BundleAccount
pub fn present_bundle_account(&self) -> BundleAccount
Present bundle account
