Enum StorageError 

#[non_exhaustive]
pub enum StorageError {
    Serialization(Error),
    Io(Error),
    LeaseNotFound {
        lease_id: LeaseId,
    },
    Backend(Error),
    Unsupported(&'static str),
    RateLimited {
        retry_after: Option<Duration>,
    },
}

An error produced by a storage backend.

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.

Serialization(Error)

JSON serialization or deserialization failed.

Io(Error)

An input/output operation failed.

LeaseNotFound

The referenced lease is no longer active.

Fields

lease_id: LeaseId

Identifier of the missing lease.

Backend(Error)

A backend-specific operation failed.

Unsupported(&'static str)

The backend does not implement an optional operation.

RateLimited

The backend rejected an operation because its rate limit was reached.

Fields

retry_after: Option<Duration>

Suggested delay before retrying, when supplied by the backend.

Implementations

impl StorageError

pub fn is_rate_limited(&self) -> bool

Returns whether this error represents backend rate limiting.

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.
