Enum GeneralizationError 

pub enum GeneralizationError {
    LiteralSubject,
    LiteralPredicate,
    BlankPredicate,
    LiteralGraph,
    TripleTermSubject,
    TripleTermPredicate,
    TripleTermGraph,
}

Reasons a GeneralizedTriple or GeneralizedQuad cannot be converted to a strict Triple / Quad.

Variants

LiteralSubject

A literal sits in subject position.

LiteralPredicate

A literal sits in predicate position.

BlankPredicate

A blank node sits in predicate position.

LiteralGraph

A literal sits in graph position.

TripleTermSubject

A triple term sits in subject position. Strict RDF 1.2 only allows triple terms in object position.

TripleTermPredicate

A triple term sits in predicate position.

TripleTermGraph

A triple term sits in graph-name position.

Trait Implementations

impl Debug for GeneralizationError

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

Formats the value using the given formatter.

impl Display for GeneralizationError

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

Formats the value using the given formatter.

impl Error for GeneralizationError

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.
