Enum CacheLookupError 

pub enum CacheLookupError {
    Io {
        source: FsError,
    },
}

Failure modes for Cache::lookup_status.

Every miss reason CACHE-016 enumerates folds into one of the CacheLookupStatus variants; only filesystem errors that are NOT a “missing entry” shape surface here.

Variants

Io

Underlying filesystem error during the read-only introspecting lookup. The wrapped FsError carries the specific path.

Fields

source: FsError

The originating filesystem error.

Trait Implementations

impl Debug for CacheLookupError

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

Formats the value using the given formatter.

impl Display for CacheLookupError

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

Formats the value using the given formatter.

impl Error for CacheLookupError

where Self: Debug + Display,

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 ErrorCompat for CacheLookupError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
