Variants

Io

Fields

path: PathBuf

source: Error

Db(DatabaseError)

Transaction(TransactionError)

Table(TableError)

Storage(StorageError)

Commit(CommitError)

NotFound

Asked for a hash the index has no record of.

Fields

hash: GraphHash

HashMismatch

The blob file’s BLAKE3 didn’t match the expected hash. Index entry is stale or the blob was tampered with — caller should drop the entry and re-fetch from upstream.

Fields

expected: GraphHash

actual: GraphHash

Validation

rkyv validation rejected the archive shape. The blob is structurally invalid for the requested type — never write what the typed border can’t read.

Fields

hash: GraphHash

message: String

BadHash

Caller passed a malformed GraphHash (wrong length / wrong base32 alphabet).

Fields

input: String

reason: &'static str

Implementations

impl Error

pub fn io(path: impl Into<PathBuf>, source: Error) -> Self

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<CommitError> for Error

fn from(source: CommitError) -> Self

Converts to this type from the input type.

impl From<DatabaseError> for Error

fn from(source: DatabaseError) -> Self

Converts to this type from the input type.

impl From<StorageError> for Error

fn from(source: StorageError) -> Self

Converts to this type from the input type.

impl From<TableError> for Error

fn from(source: TableError) -> Self

Converts to this type from the input type.

impl From<TransactionError> for Error

fn from(source: TransactionError) -> Self

Converts to this type from the input type.
