    AlreadyLocked(PathBuf),
    MalformedFormat(PathBuf),
    UnsupportedFormat {
        found: u16,
        supported: u16,

}

Failure while opening or initializing a Hyphae data directory.

Variants

AlreadyLocked(PathBuf)

Another writer already owns the directory lock.

MalformedFormat(PathBuf)

The FORMAT marker does not match the canonical representation.

UnsupportedFormat

The directory was created by a newer, unsupported disk format.

Fields

found: u16

Version found in FORMAT.

supported: u16

Highest version understood by this binary.

Manifest(ManifestError)

The immutable storage manifest could not be loaded or initialized.

Io

A filesystem operation failed.

Fields

action: &'static str

Operation that failed.

path: PathBuf

Path involved in the operation.

source: Error

Underlying operating-system error.

Trait Implementations

impl Debug for DataDirectoryError

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

Formats the value using the given formatter.

impl Display for DataDirectoryError

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

Formats the value using the given formatter.

impl Error for DataDirectoryError

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.

impl From<DataDirectoryError> for StorageError

fn from(source: DataDirectoryError) -> Self

Converts to this type from the input type.

impl From<ManifestError> for DataDirectoryError

fn from(source: ManifestError) -> Self

Converts to this type from the input type.
