Struct CacheAccount

pub struct CacheAccount {
    pub account: Option<PlainAccount>,
    pub status: AccountStatus,
}

Cache account contains plain state that gets updated at every transaction when evm output is applied to CacheState.

Fields

account: Option<PlainAccount>

status: AccountStatus

Implementations

impl CacheAccount

pub fn new_loaded( info: AccountInfo, storage: HashMap<Uint<256, 4>, Uint<256, 4>, RandomState>, ) -> CacheAccount

Create new account that is loaded from database.

pub fn new_loaded_empty_eip161( storage: HashMap<Uint<256, 4>, Uint<256, 4>, RandomState>, ) -> CacheAccount

Create new account that is loaded empty from database.

pub fn new_loaded_not_existing() -> CacheAccount

Loaded not existing account.

pub fn new_newly_created( info: AccountInfo, storage: HashMap<Uint<256, 4>, Uint<256, 4>, RandomState>, ) -> CacheAccount

Create new account that is newly created

pub fn new_destroyed() -> CacheAccount

Create account that is destroyed.

pub fn new_changed( info: AccountInfo, storage: HashMap<Uint<256, 4>, Uint<256, 4>, RandomState>, ) -> CacheAccount

Create changed account

pub fn is_some(&self) -> bool

Return true if account is some

pub fn storage_slot(&self, slot: Uint<256, 4>) -> Option<Uint<256, 4>>

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, HashMap<Uint<256, 4>, Uint<256, 4>, RandomState>)>, AccountStatus)

Dissolve account into components.

pub fn touch_create_pre_eip161( &mut self, storage: HashMap<Uint<256, 4>, StorageSlot, RandomState>, ) -> 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: HashMap<Uint<256, 4>, StorageSlot, RandomState>, ) -> 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: HashMap<Uint<256, 4>, StorageSlot, RandomState>, ) -> TransitionAccount

Trait Implementations

impl Clone for CacheAccount

fn clone(&self) -> CacheAccount

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CacheAccount

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

Formats the value using the given formatter.

impl From<BundleAccount> for CacheAccount

fn from(account: BundleAccount) -> CacheAccount

Converts to this type from the input type.

impl PartialEq for CacheAccount

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

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
