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.

Io(String)

Serde(Error)

Parquet(String)

Invalid(String)

Lance(String)

QueryError(String)

InvalidState(String)

A storage resource is in an unexpected state (e.g. the metadata path passed to a save_* call does not match the instance metadata path).

UnsupportedFormat(String)

A filetype does not map to a known storage format.

IPC(String)

An Arrow-IPC codec error (#142): file/stream write, read or schema mismatch surfaced by the arrow-ipc writer/reader.

UnsupportedFiletype(String)

A key/filetype is not recognised as one of the supported file types.

DimensionMismatch

Dimensions recorded in schema metadata do not match the dimensions recorded in storage metadata.

Fields

expected: String

found: String

Overflow(String)

A numeric value exceeds the range of the storage type it is written to.

LockWouldBlock

A non-blocking lock acquisition would block: the advisory lock file is held by another cooperating writer. Distinctly matchable so fail-fast consumers can map contention to their own taxonomy (#105).

Fields

path: PathBuf

Trait Implementations

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

Formats the value using the given formatter.

impl Error for StorageError

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.
