pub enum StorageError {
    Io(Error),
    Serde(Error),
    ChecksumMismatch(String),
    NotFound(String),
    InvalidKey(String),
}

Errors raised by the storage layer.

Variants

Io(Error)

Underlying filesystem error.

Serde(Error)

(De)serialization failure.

ChecksumMismatch(String)

The persisted checksum did not match the data on disk (corruption).

NotFound(String)

The requested key does not exist.

InvalidKey(String)

A key contained characters that are unsafe for the filesystem.

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.
