Enum StorageError 

pub enum StorageError {
    ConnectionFailed {
        message: String,
    },
    OperationFailed {
        message: String,
    },
    Serialization {
        message: String,
    },
    BackendUnavailable,
}

Storage backend errors.

Covers connectivity, query execution, and serialization issues for all storage backends (Memory, PostgreSQL, MySQL, Redis, SQLite).

Variants

ConnectionFailed

Could not establish a connection to the storage backend.

Fields

message: String

OperationFailed

A read or write operation against the store failed.

Fields

message: String

Serialization

Data could not be serialized to or deserialized from the storage format.

Fields

message: String

BackendUnavailable

The configured storage backend is unreachable or not initialized.

Implementations

impl StorageError

pub fn connection_failed(message: impl Into<String>) -> Self

Create a new connection failed error.

Example

use auth_framework::errors::StorageError;

let err = StorageError::connection_failed("connection refused");
assert!(err.to_string().contains("connection refused"));

pub fn operation_failed(message: impl Into<String>) -> Self

Create a new operation failed error.

Example

use auth_framework::errors::StorageError;

let err = StorageError::operation_failed("table not found");
assert!(err.to_string().contains("table not found"));

pub fn serialization(message: impl Into<String>) -> Self

Create a new serialization error.

Example

use auth_framework::errors::StorageError;

let err = StorageError::serialization("invalid JSON");
assert!(err.to_string().contains("invalid JSON"));

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<StorageError> for AuthError

fn from(source: StorageError) -> Self

Converts to this type from the input type.
