Implementations

impl Account

pub fn new_not_existing() -> Account

Creates new account and mark it as non existing.

pub fn state_clear_aware_is_empty(&self, spec: SpecId) -> bool

Checks if account is empty and check if empty state before spurious dragon hardfork.

pub fn mark_selfdestruct(&mut self)

Marks the account as self destructed.

pub fn unmark_selfdestruct(&mut self)

Unmarks the account as self destructed.

pub fn is_selfdestructed(&self) -> bool

Is account marked for self destruct.

pub fn mark_touch(&mut self)

Marks the account as touched

pub fn unmark_touch(&mut self)

Unmarks the touch flag.

pub fn is_touched(&self) -> bool

If account status is marked as touched.

pub fn mark_created(&mut self)

Marks the account as newly created.

pub fn unmark_created(&mut self)

Unmarks the created flag.

pub fn mark_cold(&mut self)

Marks the account as cold.

pub fn mark_warm(&mut self) -> bool

Marks the account as warm and return true if it was previously cold.

pub fn is_loaded_as_not_existing(&self) -> bool

Is account loaded as not existing from database.

This is needed for pre spurious dragon hardforks where existing and empty were two separate states.

pub fn is_created(&self) -> bool

Is account newly created in this transaction.

pub fn is_empty(&self) -> bool

Is account empty, check if nonce and balance are zero and code is empty.

pub fn changed_storage_slots( &self, ) -> impl Iterator<Item = (&Uint<256, 4>, &EvmStorageSlot)>

Returns an iterator over the storage slots that have been changed.

See also EvmStorageSlot::is_changed.

pub fn with_info(self, info: AccountInfo) -> Account

Sets account info and returns self for method chaining.

pub fn with_storage<I>(self, storage_iter: I) -> Account

where I: Iterator<Item = (Uint<256, 4>, EvmStorageSlot)>,

Populates storage from an iterator of storage slots and returns self for method chaining.

pub fn with_selfdestruct_mark(self) -> Account

Marks the account as self destructed and returns self for method chaining.

pub fn with_touched_mark(self) -> Account

Marks the account as touched and returns self for method chaining.

pub fn with_created_mark(self) -> Account

Marks the account as newly created and returns self for method chaining.

pub fn with_cold_mark(self) -> Account

Marks the account as cold and returns self for method chaining.

pub fn with_warm_mark(self) -> (Account, bool)

Marks the account as warm (not cold) and returns self for method chaining. Also returns whether the account was previously cold.

pub fn with_warm(self) -> Account

Variant of with_warm_mark that doesn’t return the previous state.

Trait Implementations

impl Clone for Account

fn clone(&self) -> Account

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Account

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

Formats the value using the given formatter.

impl Default for Account

fn default() -> Account

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Account

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Account> for Account

fn from(value: Account) -> Account

Converts to this type from the input type.

impl From<AccountInfo> for Account

fn from(info: AccountInfo) -> Account

Converts to this type from the input type.

impl PartialEq for Account

fn eq(&self, other: &Account) -> 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 Account

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 Account

impl StructuralPartialEq for Account

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.
