Struct BundleAccount

pub struct BundleAccount {
    pub info: Option<AccountInfo>,
    pub original_info: Option<AccountInfo>,
    pub storage: HashMap<Uint<256, 4>, StorageSlot, RandomState>,
    pub status: AccountStatus,
}

Account information focused on creating of database changesets and Reverts.

Status is needed as to know from what state we are applying the TransitionAccount.

Original account info is needed to know if there was a change. Same thing for storage with original value.

On selfdestruct storage original value is ignored.

Fields

info: Option<AccountInfo>

original_info: Option<AccountInfo>

storage: HashMap<Uint<256, 4>, StorageSlot, RandomState>

Contains both original and present state. When extracting changeset we compare if original value is different from present value. If it is different we add it to changeset.

If Account was destroyed we ignore original value and compare present state with U256::ZERO.

status: AccountStatus

Account status.

Implementations

impl BundleAccount

pub fn new( original_info: Option<AccountInfo>, present_info: Option<AccountInfo>, storage: HashMap<Uint<256, 4>, StorageSlot, RandomState>, status: AccountStatus, ) -> BundleAccount

Create new BundleAccount.

pub fn size_hint(&self) -> usize

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

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

Return storage slot if it exists.

In case we know that account is newly created or destroyed, return Some(U256::ZERO)

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

Fetch account info if it exist.

pub fn was_destroyed(&self) -> bool

Was this account destroyed.

pub fn is_info_changed(&self) -> bool

Return true of account info was changed.

pub fn is_contract_changed(&self) -> bool

Return true if contract was changed

pub fn revert(&mut self, revert: AccountRevert) -> bool

Revert account to previous state and return true if account can be removed.

pub fn update_and_create_revert( &mut self, transition: TransitionAccount, ) -> Option<AccountRevert>

Update to new state and generate AccountRevert that if applied to new state will revert it to previous state. If no revert is present, update is noop.

Trait Implementations

impl Clone for BundleAccount

fn clone(&self) -> BundleAccount

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BundleAccount

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BundleAccount

fn deserialize<__D>( __deserializer: __D, ) -> Result<BundleAccount, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<BundleAccount> for CacheAccount

fn from(account: BundleAccount) -> CacheAccount

Converts to this type from the input type.

impl PartialEq for BundleAccount

fn eq(&self, other: &BundleAccount) -> 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.

impl Serialize for BundleAccount

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for BundleAccount

impl StructuralPartialEq for BundleAccount

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.
