Errors produced by Oxiland.

The variant set is closed for 1.0 intent (ADR-020). New categories require an ADR. Unsupported Redland factories and options surface as Error::Unsupported rather than silent success.

Variants

InvalidRdf(String)

An RDF term or IRI was invalid.

Parse(ParseError)

An RDF document could not be parsed.

Serialize(String)

An RDF document could not be serialized.

SparqlParse(String)

A SPARQL query could not be parsed.

SparqlEvaluation(String)

A SPARQL query could not be evaluated.

Storage(String)

The storage backend failed.

Unsupported(String)

A requested Redland-compatible feature is unsupported.

Io(Error)

A filesystem or byte-stream I/O failure.

OpenStore

A filesystem-backed store could not be opened.

Fields

path: PathBuf

Store path.

message: String

Backend error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ParseError> for Error

fn from(source: ParseError) -> Self

Converts to this type from the input type.
