Coarse, exhaustive classification of a StoreError, stable for hosts that map engine failures onto their own status codes. Every variant of StoreError maps to exactly one kind; adding a variant is a compile error here until it is classified.

Variants

Io

An operating-system or filesystem operation failed.

InvalidArgument

A caller-supplied path or schema was invalid.

StoreBusy

Another process or handle owns the store’s writer lock.

Unsupported

The requested mode or operation is unsupported.

Corrupt

Persisted data failed validation.

BudgetExceeded

A configured memory, disk, or work budget was exceeded.

OutOfMemory

A checked allocation could not be reserved.

DimensionMismatch

Vector dimensions disagreed.

EpochMismatch

The declared epoch differs from the persisted identity.

EpochUndeclared

The store requires an epoch declaration and none was supplied.

EpochUnstamped

An epoch was declared for a store with no stamped identity.

Internal

An internal invariant failed.

EmptyBatch

A batch or active segment was empty.

Cancelled

Cooperative cancellation stopped the operation.

ReadOnly

The store is read-only.

Closing

The store is closing.

Closed

The store is closed.

Panic

A background or query-pool thread panicked.

Synchronization

A synchronization primitive was poisoned or unavailable.
