status: AccountStatus

Implementations

impl CacheAccount

pub fn new_loaded(info: AccountInfo, storage: PlainStorage) -> Self

Create new account that is loaded from database.

pub fn new_loaded_empty_eip161(storage: PlainStorage) -> Self

Create new account that is loaded empty from database.

pub fn new_loaded_not_existing() -> Self

Loaded not existing account.

pub fn new_newly_created(info: AccountInfo, storage: PlainStorage) -> Self

Create new account that is newly created

pub fn new_destroyed() -> Self

Create account that is destroyed.

pub fn new_changed(info: AccountInfo, storage: PlainStorage) -> Self

Create changed account

pub fn is_some(&self) -> bool

Return true if account is some

pub fn storage_slot(&self, slot: U256) -> Option<U256>

Return storage slot if it exist.

pub fn account_info(&self) -> Option<AccountInfo>

Fetch account info if it exist.

pub fn into_components( self, ) -> (Option<(AccountInfo, PlainStorage)>, AccountStatus)

Dissolve account into components.

pub fn touch_create_pre_eip161( &mut self, storage: StorageWithOriginalValues, ) -> Option<TransitionAccount>

Account got touched and before EIP161 state clear this account is considered created.

pub fn touch_empty_eip161(&mut self) -> Option<TransitionAccount>

Touch empty account, related to EIP-161 state clear.

This account returns the Transition that is used to create the BundleState.

pub fn selfdestruct(&mut self) -> Option<TransitionAccount>

Consume self and make account as destroyed.

Set account as None and set status to Destroyer or DestroyedAgain.

pub fn newly_created( &mut self, new_info: AccountInfo, new_storage: StorageWithOriginalValues, ) -> TransitionAccount

Newly created account.

pub fn increment_balance(&mut self, balance: u128) -> Option<TransitionAccount>

Increment balance by balance amount. Assume that balance will not overflow or be zero.

Note: only if balance is zero we would return None as no transition would be made.

pub fn drain_balance(&mut self) -> (u128, TransitionAccount)

Drain balance from account and return drained amount and transition.

Used for DAO hardfork transition.

pub fn change( &mut self, new: AccountInfo, storage: StorageWithOriginalValues, ) -> TransitionAccount

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

Tests for self and other values to be equal, and is used by ==.

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