Variants

InvalidDatatype(String)

Tuple Fields

0: String

Datatypes must be IRIs.

InvalidIri(String)

Tuple Fields

0: String

err: String

What is wrong with tag.

The language tags of literals must apply to BCP47.

InvalidLexicalValue

Fields

lex: String

The faulty lexical value.

dt: String

The literal datatype IRI.

source: Box<dyn Error>

The underlying error.

The lexical value of a literal can not be interpreted according to its datatype

InvalidVariableName(String)

Tuple Fields

0: String

Names of variables must apply to SPARQL’s production rules.

InvalidBlankNodeId(String)

Tuple Fields

0: String

Trait Implementations

impl Debug for TermError

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

Formats the value using the given formatter.

impl Display for TermError

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

Formats the value using the given formatter.

impl Error for TermError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<Infallible> for TermError

fn from(_: Infallible) -> TermError

Performs the conversion.
