Type Alias JournaledState

Aliased Type

    pub journal: Vec<JournalEntry>,
    pub transaction_id: usize,

    pub warm_coinbase_address: Option<Address>,

}

Fields

state: HashMap<Address, Account, RandomState>

The current state

transient_storage: HashMap<(Address, Uint<256, 4>), Uint<256, 4>, RandomState>

Transient storage that is discarded after every transaction.

See EIP-1153.

logs: Vec<Log>

Emitted logs

depth: usize

The current call stack depth

journal: Vec<JournalEntry>

The journal of state changes, one for each transaction

transaction_id: usize

Global transaction id that represent number of transactions executed (Including reverted ones). It can be different from number of journal_history as some transaction could be reverted or had a error on execution.

This ID is used in Self::state to determine if account/storage is touched/warm/cold.

spec: SpecId

The spec ID for the EVM. Spec is required for some journal entries and needs to be set for JournalInner to be functional.

If spec is set it assumed that precompile addresses are set as well for this particular spec.

This spec is used for two things:

• EIP-161: Prior to this EIP, Ethereum had separate definitions for empty and non-existing accounts.
• EIP-6780: SELFDESTRUCT only in same transaction

warm_preloaded_addresses: HashSet<Address, RandomState>

Warm loaded addresses are used to check if loaded address should be considered cold or warm loaded when the account is first accessed.

Note that this not include newly loaded accounts, account and storage is considered warm if it is found in the State.

warm_coinbase_address: Option<Address>

Warm coinbase address, stored separately to avoid cloning preloaded addresses.

precompiles: HashSet<Address, RandomState>

Precompile addresses

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.
