Enum PackageCacheLayerError

#[non_exhaustive]
pub enum PackageCacheLayerError {
    InvalidPackage,
    PackageNotFound,
    LockError(String, Error),
    Cancelled,
    FetchError(Arc<dyn Error + Send + Sync>),
    OtherError(Box<dyn Error + Send + Sync>),
}

Errors specific to individual layers in the PackageCache

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.

InvalidPackage

The package is invalid

PackageNotFound

The package was not found in this layer

LockError(String, Error)

A locking error occurred

Cancelled

The operation was cancelled

FetchError(Arc<dyn Error + Send + Sync>)

An error occurred while fetching the package.

OtherError(Box<dyn Error + Send + Sync>)

Trait Implementations

impl Debug for PackageCacheLayerError

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

Formats the value using the given formatter.

impl Display for PackageCacheLayerError

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

Formats the value using the given formatter.

impl Error for PackageCacheLayerError

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.
