Trait that contains database and journal of all changes that were made to the account.

Required Methods

fn account(&self) -> &Account

Returns the account.

fn sload( &mut self, key: Uint<256, 4>, skip_cold_load: bool, ) -> Result<StateLoad<&mut EvmStorageSlot>, JournalLoadError<ErasedError>>

Sloads the storage slot and returns its mutable reference

fn sstore( &mut self, key: Uint<256, 4>, new: Uint<256, 4>, skip_cold_load: bool, ) -> Result<StateLoad<SStoreResult>, JournalLoadError<ErasedError>>

Loads the storage slot and stores the new value

fn load_code(&mut self) -> Result<&Bytecode, JournalLoadError<ErasedError>>

Loads the code of the account. and returns it as reference.

fn balance(&self) -> &Uint<256, 4>

Returns the balance of the account.

fn nonce(&self) -> u64

Returns the nonce of the account.

fn code_hash(&self) -> &FixedBytes<32>

Returns the code hash of the account.

fn code(&self) -> Option<&Bytecode>

Returns the code of the account.

fn touch(&mut self)

Touches the account.

fn unsafe_mark_cold(&mut self)

Marks the account as cold without making a journal entry.

Changing account without journal entry can be a footgun as reverting of the state change would not happen without entry. It is the reason why this function has an unsafe prefix.

If account is in access list, it would still be marked as warm if account get accessed again.

fn set_balance(&mut self, balance: Uint<256, 4>)

Sets the balance of the account.

If balance is the same, we don’t add a journal entry.

Touches the account in all cases.

fn set_extension(&mut self, extension: AccountExtension)

Available on crate feature account-ext only.

Sets the chain-specific payload, touching the account and journaling the previous value.

fn incr_balance(&mut self, balance: Uint<256, 4>) -> bool

Increments the balance of the account.

Touches the account in all cases.

fn decr_balance(&mut self, balance: Uint<256, 4>) -> bool

Decrements the balance of the account.

Touches the account in all cases.

fn bump_nonce(&mut self) -> bool

Bumps the nonce of the account.

Touches the account in all cases.

Returns true if nonce was bumped, false if nonce is at the max value.

fn set_nonce(&mut self, nonce: u64)

Set the nonce of the account and create a journal entry.

Touches the account in all cases.

fn unsafe_set_nonce(&mut self, nonce: u64)

Set the nonce of the account without creating a journal entry.

Changing account without journal entry can be a footgun as reverting of the state change would not happen without entry. It is the reason why this function has an unsafe prefix.

fn set_code(&mut self, code_hash: FixedBytes<32>, code: Bytecode)

Sets the code of the account.

Touches the account in all cases.

fn set_code_and_hash_slow(&mut self, code: Bytecode)

Sets the code of the account. Calculates hash of the code.

Touches the account in all cases.

fn delegate(&mut self, address: Address)

Delegates the account to another address (EIP-7702).

This touches the account, sets the code to the delegation designation, and bumps the nonce.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
