Validation or consistency error from ranked search or traversal.

Variants

EmptyQuery

Search text is empty after normalization.

InvalidPagination

Search pagination is outside the supported bound.

InvalidScore

A supplied score is not finite or is negative.

Fields

signal: &'static str

Name of the invalid signal.

node: String

Node carrying the invalid score.

DuplicateNode(String)

More than one node has the same identifier.

DuplicateEdge(String)

More than one edge has the same identifier.

DanglingEdge

An edge endpoint is absent from the supplied graph.

Fields

edge: String

Stable edge identifier.

node: String

Missing node identifier.

UnknownAnchor(String)

A traversal anchor is absent from the supplied graph.

InvalidTraversalLimits

One or more traversal limits are zero or exceed hard bounds.

InvalidMinimumConfidence

Minimum confidence is not finite or lies outside zero through one.

InvalidEdgeConfidence(String)

An edge has invalid confidence for conservative weighting.

InvalidEdgeCost(EdgeKind)

An edge-kind cost is not finite and strictly positive.

InconsistentPath(String)

Internal path reconstruction found inconsistent graph state.

Trait Implementations

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Error for QueryError

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 QueryError

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

Equality operator ==.

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

Inequality operator !=.
