Enum CachekitError 

#[non_exhaustive]
pub enum CachekitError {
    Backend(BackendError),
    Serialization(String),
    Encryption(String),
    Config(String),
    PayloadTooLarge {
        size: usize,
        limit: usize,
    },
    InvalidKey(String),
}

Top-level error type for all CacheKit 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.

Backend(BackendError)

An error originating from the cache backend.

Serialization(String)

Serialization or deserialization failed.

Encryption(String)

Encryption or decryption failed.

Config(String)

Configuration is invalid or missing required values.

PayloadTooLarge

The payload exceeds the maximum allowed size.

Fields

size: usize

Actual payload size in bytes.

limit: usize

Maximum allowed size in bytes.

InvalidKey(String)

The cache key is invalid (empty, too long, or contains illegal bytes).

Trait Implementations

impl Debug for CachekitError

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

Formats the value using the given formatter.

impl Display for CachekitError

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

Formats the value using the given formatter.

impl Error for CachekitError

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<BackendError> for CachekitError

fn from(source: BackendError) -> Self

Converts to this type from the input type.
