This error is raised when the creation of a term fails.

Variants

InvalidDatatype(String)

Datatypes must be IRIs.

InvalidIri(String)

The IRI of a term must apply to RFC 3987.

IsSuffixed

An IRI must be represented by one TermData to be able to convert it to a Namespace.

InvalidLanguageTag

The language tags of literals must apply to BCP47.

Fields of InvalidLanguageTag

tag: String

The provided, faulty language tag.

err: String

What is wrong with tag.

InvalidLexicalValue

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

Fields of InvalidLexicalValue

lex: String

The faulty lexical value.

dt: String

The literal datatype IRI.

source: Box<dyn Error>

The underlying error.

InvalidVariableName(String)

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

InvalidBlankNodeId(String)

Names of variables must apply to N3's production rules.

UnsupportedKind(String)

Raised when failing to convert a term into another type

UnsupportedDatatype(String)

Raised when failing to convert a literal into a native type

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()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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.
