}

The one error type of the tablet surface: descriptors, layout, and ownership.

Variants

Metadata(ClusterError)

A durable metadata file failed the node.rs idiom’s checks (unknown version, corrupt payload, I/O). Always fail closed.

MissingMetadata(PathBuf)

No tablet.json exists where a tablet was expected.

TabletMismatch

The persisted metadata names a different tablet or Raft group than the directory it lives in.

Fields

path: PathBuf

The tablet directory.

expected: TabletId

Tablet id implied by the directory name.

found: TabletId

Tablet id the metadata names.

expected_group: RaftGroupId

Raft group id implied by the layout.

found_group: RaftGroupId

Raft group id the metadata names.

MetadataConflict(PathBuf)

create found existing, different metadata; never silently replaced.

InvalidStateTransition

The requested TabletState transition is not in the graph.

Fields

tablet: TabletId

The tablet whose state was to change.

from: TabletState

Current state.

to: TabletState

Requested target state.

InvalidBounds(String)

Empty or inverted partition bounds.

InvalidDescriptor(String)

A TabletDescriptor failed structural validation.

Partition(PartitionError)

Partitioning failed.

AlreadyOwned

Another tablet storage core in this process already owns the tablet directory (spec section 4.1; mirrors S1A-002).

Fields

tablet: TabletId

Tablet holding the reservation.

path: PathBuf

The contested tablet directory.

Trait Implementations

impl Debug for TabletError

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

Formats the value using the given formatter.

impl Display for TabletError

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

impl Error for TabletError

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
