Structured failure from transactional artifact caching.

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.

InvalidSpec

The caller supplied an incomplete, ambiguous, or unsafe specification.

Fields

message: String

Io

A filesystem operation failed.

Fields

operation: &'static str

path: PathBuf

source: Error

InputsChangedDuringPreparation

Inputs repeatedly changed while preparing a stable cache acquisition.

Fields

before: InputDigest

after: InputDigest

InputsChangedDuringBuild

Inputs changed while the caller owned a build transaction.

Fields

before: InputDigest

after: InputDigest

InvalidOutputs

One or more declared staged outputs were missing or failed validation.

Fields

outputs: Vec<(String, PathBuf)>

UnknownOutput

A logical output name was not declared by the transaction specification.

Fields

name: String

FailedTransactionCleanup

Transaction failure cleanup also failed.

Fields

transaction_error: Box<Self>

path: PathBuf

source: Error

Trait Implementations

impl Debug for ArtifactCacheError

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

Formats the value using the given formatter.

impl Display for ArtifactCacheError

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

Formats the value using the given formatter.

impl Error for ArtifactCacheError

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.
