Enum CheckpointError 

pub enum CheckpointError {
    WrongGenerationKind,
    WrongFileTableKind,
    DuplicateParent,
    CrossVolumeMerge,
    RootIdentityMismatch,
    Storage(ObjectStoreError),
    Decode(CanonicalDecodeError),
    Work(WorkError),
}

Immutable checkpoint construction failures.

Variants

WrongGenerationKind

Base or merge parent is not a generation-root object.

WrongFileTableKind

Candidate file table has the wrong object kind.

DuplicateParent

Merge repeats its base as second parent.

CrossVolumeMerge

Merge parent belongs to another volume.

RootIdentityMismatch

Merge parents disagree on the stable volume-root file identity.

Storage(ObjectStoreError)

Immutable object storage failed.

Decode(CanonicalDecodeError)

Canonical generation encoding/decoding failed.

Work(WorkError)

Exact work exceeded or overflowed its budget.

Trait Implementations

impl Debug for CheckpointError

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

Formats the value using the given formatter.

impl Display for CheckpointError

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

Formats the value using the given formatter.

impl Error for CheckpointError

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.
