Enum SnapshotError

#[non_exhaustive]
pub enum SnapshotError {
    Encode(String),
    Decode(String),
    VersionMismatch {
        expected: u32,
        got: u32,
    },
    InvalidReference(u32),
    RestoreError(String),
}

Errors that can occur during snapshot save/restore.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Encode(String)

Bincode encoding failed.

Decode(String)

Bincode decoding failed.

VersionMismatch

The snapshot was created with a different format version.

Fields

expected: u32

The version this build expects.

got: u32

The version found in the snapshot data.

InvalidReference(u32)

A serialized object reference points outside the object table.

RestoreError(String)

A GC object could not be reconstructed (e.g. unknown TypeDescriptor).

Trait Implementations

impl Debug for SnapshotError

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

Formats the value using the given formatter.

impl Display for SnapshotError

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

Formats the value using the given formatter.

impl Error for SnapshotError

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.
