Enum RelationshipSelectionError

pub enum RelationshipSelectionError {
    InvalidRequest,
    DuplicateCandidate,
    DuplicateEvidence,
    ResponseRequestMismatch,
    InexactEvidence,
    Unavailable(String),
}

Failure to select comparison candidates conclusively.

Variants

InvalidRequest

The requested relationship or candidate universe is malformed.

DuplicateCandidate

The candidate universe or response contains the same object more than once.

DuplicateEvidence

A response repeats one evidence locator.

ResponseRequestMismatch

Returned data belongs to another request or escapes its candidate universe.

InexactEvidence

A conclusive selection lacks exact, reviewable completeness evidence.

Unavailable(String)

The source cannot currently provide a conclusive selection.

Trait Implementations

impl Clone for RelationshipSelectionError

fn clone(&self) -> RelationshipSelectionError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RelationshipSelectionError

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

Formats the value using the given formatter.

impl Display for RelationshipSelectionError

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

Formats the value using the given formatter.

impl Error for RelationshipSelectionError

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 RelationshipSelectionError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
