pub enum StorageError {
    ReadOnly(ReadOnlyViolation),
    Io(Error),
    Doublets(String),
    Corrupt(String),
}

Storage-level errors returned by LinkStore implementations.

Variants

ReadOnly(ReadOnlyViolation)

A write was attempted through a read-only storage handle.

Io(Error)

File I/O failed while opening or maintaining a file-backed store.

Doublets(String)

The optional doublets backend returned an error.

Corrupt(String)

Stored bytes do not match the meta-language storage schema.

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)>

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<Error> for StorageError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<ReadOnlyViolation> for StorageError

fn from(error: ReadOnlyViolation) -> Self
