}

Errors that can occur during snapshot loading.

Variants

IoError(String)

I/O error during load.

DecodeError(String)

The snapshot could not be decoded.

MappingError(SnapshotMappingError)

The decoded snapshot violated mapping/parity invariants.

IncompatibleVersion

The snapshot version is incompatible.

Fields

expected: u32

Snapshot version expected by the loader configuration.

found: u32

Snapshot version found in the persisted snapshot frame.

CrcMismatch

The snapshot CRC-32 checksum does not match the payload.

Fields

expected: u32

CRC-32 checksum stored in the snapshot frame.

actual: u32

CRC-32 checksum computed from the payload bytes.

NotFound

The snapshot file does not exist.

Trait Implementations

impl Clone for SnapshotLoaderError

fn clone(&self) -> SnapshotLoaderError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapshotLoaderError

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

Formats the value using the given formatter.

impl Display for SnapshotLoaderError

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

Formats the value using the given formatter.

impl Error for SnapshotLoaderError

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<Error> for SnapshotLoaderError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl PartialEq for SnapshotLoaderError

fn eq(&self, other: &SnapshotLoaderError) -> 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.
