Enum CacheError 

#[non_exhaustive]
pub enum CacheError {
    LimitExceeded,
    InvalidOperation,
    Unsupported,
    Timeout,
    Other(FastlyStatus),
}

Errors arising from cache 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.

LimitExceeded

Operation failed due to a limit.

InvalidOperation

Operation was not valid to be performed given the state of the cached item.

Unsupported

Cache operation is not supported.

Timeout

The cache operation did not complete within the timeout supplied by the caller.

This is returned by timeout-bounded operations such as PendingTransaction::wait_for() when the timeout elapses before the operation completes.

Other(FastlyStatus)

An unknown error occurred.

Trait Implementations

impl Debug for CacheError

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

Formats the value using the given formatter.

impl Display for CacheError

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

Formats the value using the given formatter.

impl Error for CacheError

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<CacheError> for CacheError

fn from(value: CacheError) -> Self

Converts to this type from the input type.

impl From<FastlyStatus> for CacheError

fn from(status: FastlyStatus) -> Self

Converts to this type from the input type.
