Enum deltalake::storage::StorageError

pub enum StorageError {
    NotFound,
    AlreadyExists(String),
    Io {
        source: Error,
    },
    FileSystemNotSupported,
    Generic(String),
    Uri {
        source: UriError,
    },
}

Error enum returned when storage backend interaction fails.

Variants

NotFound

The requested object does not exist.

AlreadyExists(String)

The object written to the storage backend already exists. This error is expected in some cases. For example, optimistic concurrency writes between multiple processes expect to compete for the same URI when writing to _delta_log.

Io

An IO error occurred while reading from the local file system.

Fields of Io

source: Error

The raw error returned when trying to read the local file.

FileSystemNotSupported

The file system represented by the scheme is not known.

Generic(String)

Wraps a generic storage backend error. The wrapped string contains the details.

Uri

Error returned when the URI is invalid. The wrapped UriError contains additional details.

Fields of Uri

source: UriError

Uri error details when the URI is invalid.

Implementations

impl StorageError

pub fn other_std_io_err(desc: String) -> Self

Creates a StorageError::Io error wrapping the provided error string.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for StorageError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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
