Errors produced by the explain queries. Wording is stable so integration tests can match on substrings.

Variants

PackageNotFound

The named package is not in the resolved graph.

Fields

name: String

candidates: Vec<String>

AmbiguousPackageName

More than one package shares the same name. This is rejected by the resolver today, but the variant is retained so future graph changes have a clear failure mode.

Fields

name: String

versions: Vec<String>

TargetNotFound

The named target does not exist in any package the user selected.

Fields

name: String

candidates: Vec<String>

AmbiguousTargetName

Multiple selected packages declare a target with the same name.

Fields

name: String

owners: Vec<String>

InvalidFeatureQuery

cabin explain feature <package/feature> query string did not contain a / separator.

Fields

query: String

FeatureNotFound

The named feature does not exist on the named package.

Fields

package: String

feature: String

candidates: Vec<String>

NoBuildConfiguration

The orchestration layer did not compute a build configuration for this package. Today this happens only when the user asks about a package outside the selected closure.

Fields

name: String

Trait Implementations

impl Debug for ExplainError

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

Formats the value using the given formatter.

impl Display for ExplainError

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

Formats the value using the given formatter.

impl Error for ExplainError

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.
