Enum BalError 

pub enum BalError {
    AccountNotFound {
        address: Address,
    },
    InvalidAccountId {
        account_id: AccountId,
    },
    SlotNotFound {
        address: Address,
        slot: Uint<256, 4>,
    },
}

Error returned when a BAL (Block Access List, EIP-7928) lookup cannot find data the caller expected to be present.

A BAL is supposed to enumerate every account and storage slot a block will touch, so when execution queries the BAL for an entry that is missing, the BAL is either malformed or being consulted for state that it does not cover. Each variant identifies which kind of lookup failed and carries the key that was queried so callers can report it.

Produced by Bal read paths (Bal::populate_account_info, Bal::populate_storage_slot, Bal::populate_storage_slot_by_account_id, Bal::account_storage, StorageBal::get, StorageBal::get_bal_writes) and surfaced through BalState / BalDatabase in revm-database-interface, where it is wrapped into EvmDatabaseError::Bal before reaching the EVM.

Variants

AccountNotFound

The address was not present in the BAL’s accounts map.

Returned by address-keyed lookups (e.g. BalState::get_account_id, BalState::storage, Bal::populate_storage_slot) when the BAL is attached but does not list this account. Means the BAL is incomplete for the access being attempted.

Fields

address: Address

Address that was not found.

InvalidAccountId

The supplied AccountId index is out of range for the BAL’s accounts map.

AccountIds are positional indices into the BAL — they are only valid for the same BAL they were obtained from. This variant indicates a stale or mismatched id was used (e.g. an id from a different BAL, or one created before the current BAL was built).

Fields

account_id: AccountId

Account id that was supplied.

SlotNotFound

The account exists in the BAL but the requested storage slot is not listed under it.

Returned by storage lookups when the account is covered by the BAL yet this particular slot was not declared. As with BalError::AccountNotFound, this indicates the BAL is incomplete for the access being attempted.

Fields

address: Address

Address of the account whose slot was missing.

slot: Uint<256, 4>

Storage slot that was not found.

Trait Implementations

impl Clone for BalError

fn clone(&self) -> BalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BalError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BalError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BalError

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

Formats the value using the given formatter.

impl Error for BalError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<ERROR> From<BalError> for EvmDatabaseError<ERROR>

fn from(error: BalError) -> EvmDatabaseError<ERROR>

Converts to this type from the input type.

impl PartialEq for BalError

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

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.
