Enum IdDriverStorageError 

#[non_exhaustive]
pub enum IdDriverStorageError {
    NotFound(String),
    CasConflict {
        expected: Option<Vec<u8>>,
        found: Option<Vec<u8>>,
    },
    Io(Box<dyn Error + Send + Sync>),
}

Error type for storage operations.

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.

NotFound(String)

The requested path was not found.

CasConflict

Compare-and-swap conflict: the expected value didn’t match.

Fields

expected: Option<Vec<u8>>

The expected value (None = expected to not exist).

found: Option<Vec<u8>>

The actual value found.

Io(Box<dyn Error + Send + Sync>)

An I/O or backend-specific error.

Implementations

impl StorageError

pub fn not_found(path: impl Into<String>) -> StorageError

Create a NotFound error for the given path.

pub fn cas_conflict( expected: Option<Vec<u8>>, found: Option<Vec<u8>>, ) -> StorageError

Create a CAS conflict error.

pub fn io<E>(e: E) -> StorageError

where E: Error + Send + Sync + 'static,

Create an I/O error from any error type.

Trait Implementations

impl AuthsErrorInfo for StorageError

fn error_code(&self) -> &'static str

Returns a unique error code string for this error variant.

fn suggestion(&self) -> Option<&'static str>

Returns an optional actionable suggestion for resolving the error.

impl Debug for StorageError

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

Formats the value using the given formatter.

impl Display for StorageError

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

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 SdkStorageError

fn from(source: StorageError) -> Self

Converts to this type from the input type.
