Cache operation failure.

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.

Io

A filesystem operation failed.

Fields

operation: &'static str

Operation that failed.

path: PathBuf

Affected path.

source: Error

Underlying operating-system error.

InsecureDirectory

A cache directory is missing, untrusted, or unsafe to traverse.

Fields

path: PathBuf

Rejected directory.

UntrustedEntry

A cache entry is not an owned regular file.

Fields

path: PathBuf

Rejected entry.

CacheHomeUnavailable

No absolute XDG cache directory or home directory is available.

InvalidApplicationId

An XDG application identifier is not one normal path component.

Fields

value: PathBuf

Rejected identifier.

InvalidGsym(Box<InvalidGsymError>)

A cache file is not valid GSYM.

BuildIdMismatch(Box<BuildIdMismatchError>)

The GSYM build identifier differs from its cache key.

InvalidFailureTtl

A negative-cache lifetime is zero or exceeds the maximum.

Fields

lifetime: Duration

Rejected cache lifetime.

maximum: Duration

Maximum accepted lifetime.

FailureExpirationUnrepresentable

A negative-cache expiration cannot be represented by the system clock.

Fields

now: SystemTime

Clock value used to calculate the expiration.

lifetime: Duration

Requested cache lifetime.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
