Enum StorageError 

pub enum StorageError {
    Database(DatabaseError),
    InvalidLayout {
        slot: U256,
        reason: &'static str,
    },
    Invariant(&'static str),
}

Errors raised by the arb-storage layer.

Database(...) is an infrastructure failure that must abort the calling block. The remaining variants signal that the stored bytes do not match the layout the type expects, which indicates either corrupted state or a version skew between layout code and on-chain data; both abort the block.

Variants

Database(DatabaseError)

The underlying state database returned an error.

InvalidLayout

A stored value violated the layout invariants of its typed wrapper (e.g. an address slot whose upper 12 bytes are non-zero).

Fields

slot: U256

The slot whose layout is invalid.

reason: &'static str

Short description of the broken invariant.

Invariant(&'static str)

A storage container detected a broken structural invariant (e.g. a queue read past next_put).

Trait Implementations

impl Clone for StorageError

fn clone(&self) -> StorageError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

Formats the value using the given formatter.

impl Error for StorageError

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 From<DatabaseError> for StorageError

fn from(source: DatabaseError) -> Self

Converts to this type from the input type.
