Implementations

impl StorageError

pub fn not_found(id: impl Into<String>) -> Self

Create a not found error.

pub fn already_exists(id: impl Into<String>) -> Self

Create an already exists error.

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

Create a validation error.

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

Create a connection error.

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

Create a query error.

pub fn timeout(duration_ms: u64) -> Self

Create a timeout error.

pub fn simulated_fault(fault_type: impl Into<String>) -> Self

Create a simulated fault error.

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

Create an internal error.

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

Create a read error (wraps query error for reads).

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

Create a write error (wraps query error for writes).

pub fn is_transient(&self) -> bool

Check if this is a transient error (can be retried).

Trait Implementations

impl Clone for StorageError

fn clone(&self) -> StorageError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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 MemoryError

fn from(err: StorageError) -> Self

Converts to this type from the input type.

impl From<StorageError> for RetrievalError

fn from(err: StorageError) -> Self

Converts to this type from the input type.
