Errors produced by the storage subsystem.

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(Error)

An I/O error occurred while accessing the filesystem.

Json(Error)

A JSON serialisation or deserialisation error.

Sqlite(Error)

A SQLite error.

GitFirstCommit(String)

The Git first-commit hash could not be determined.

Migration

A migration step failed.

Fields

from: u32

Source schema version.

to: u32

Target schema version.

reason: String

Human-readable reason for the failure.

NotWritable

The storage directory is not writable.

Fields

path: String

Path that could not be written.

InvalidConfig

The config file is invalid.

Fields

path: String

Path to the config file.

reason: String

Human-readable reason.

Env(VarError)

An environment variable could not be read.

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.
