Variants

EmptyOwner

Owner identity is empty.

EmptyOwnerGraph(String)

Owner graph has no conclusions.

ConclusionWithoutFacts(ConclusionId)

A conclusion has no semantic dependency.

DuplicateConclusion(ConclusionId)

One owner declared a conclusion twice.

DuplicateOwner

Two owners claimed one conclusion.

Fields

conclusion: ConclusionId

Conflicting conclusion.

first: String

First owner.

second: String

Second owner.

UnknownFact

A graph referenced a fact outside the sealed world.

Fields

conclusion: ConclusionId

Referring conclusion.

fact: FactId

Missing fact.

EmptyClosure

No owner graph contributed a conclusion.

UnknownConclusion(ConclusionId)

Requested conclusion is absent.

Unrelated

Conclusion does not consume the requested fact.

Fields

conclusion: ConclusionId

Requested conclusion.

fact: FactId

Requested fact.

Trait Implementations

impl Clone for ClosureError

fn clone(&self) -> ClosureError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClosureError

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

Formats the value using the given formatter.

impl Display for ClosureError

Formats the value using the given formatter.

impl Eq for ClosureError

impl Error for ClosureError

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.

impl PartialEq for ClosureError

fn eq(&self, other: &ClosureError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
