Error type describing the sorts of errors guppy can return.

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.

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

An error occurred while executing cargo metadata.

MetadataParseError(Error)

An error occurred while parsing cargo metadata JSON.

MetadataSerializeError(Error)

An error occurred while serializing cargo metadata JSON.

PackageGraphConstructError(String)

An error occurred while constructing a PackageGraph from parsed metadata.

UnknownPackageId(PackageId)

A package ID was unknown to this PackageGraph.

UnknownFeatureId(PackageId, String)

A feature ID was unknown to this FeatureGraph.

UnknownWorkspacePath(Utf8PathBuf)

A package specified by path was unknown to this workspace.

UnknownWorkspaceName(String)

A package specified by name was unknown to this workspace.

TargetSpecError(String, TargetSpecError)

An error was returned by target-spec.

PackageGraphInternalError(String)

An internal error occurred within this PackageGraph.

FeatureGraphInternalError(String)

An internal error occurred within this FeatureGraph.

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, f: &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.
