Every error returned by this crate. Each variant carries enough context to identify what failed; Display (via thiserror) renders the same message shown in the /// line above each variant.

Variants

DatasetNotFound(String)

The named dataset doesn’t exist in this store.

DatasetAlreadyExists(String)

A dataset with this name was already created in this store.

ArrayNotFound(String)

The named array isn’t defined in the relevant dataset.

ArrayAlreadyExists(String)

An array with this name was already defined in the dataset.

StoreNotFound

Atlas::open / open_path was called against a location with no metadata file (neither atlas.json nor any of the atlas.msgpack* variants).

InvalidName(String)

Dataset or array name failed validation. Names must be non-empty, cannot contain /, .., or ., and cannot start with _.

ArrayFormat(Error)

Underlying array-format failure — see the wrapped error for the specific block/codec/storage problem.

Io(Error)

Local filesystem I/O failure (used by create_path / open_path).

Meta(Error)

Failed to parse the JSON form of the store metadata.

MetaEncode(Error)

Failed to encode store metadata to MessagePack (atlas.msgpack / atlas.msgpack.zst / atlas.msgpack.lz4).

MetaDecode(Error)

Failed to decode the MessagePack form of the store metadata.

MetaLz4Decompress(DecompressError)

Failed to LZ4-decompress the on-disk metadata file (atlas.json.lz4 / atlas.msgpack.lz4).

ObjectStore(Error)

Underlying object_store failure — bubbled up from the backend (local FS, S3, GCS, Azure, in-memory).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
