Enum IngestError 

#[non_exhaustive]
pub enum IngestError {
    Line(usize, &'static str),
    Turtle(String),
    TriG(String),
    RdfXml(String),
    UnknownFormat(String),
    Rdf12TurtleUnavailable,
    Io(String),
    InvalidIri {
        location: String,
        token: String,
        reason: &'static str,
    },
}

Why an ingest failed. Parser errors from oxttl/oxrdfxml and I/O errors are flattened to their Display string rather than wrapped: the variants then carry no foreign types, which keeps the error usable from the wasm bindings and stable across upstream parser upgrades.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Line(usize, &'static str)

A malformed N-Triples/N-Quads line: its 1-based line number and a short reason ("bad subject", "missing trailing '.'", …).

Turtle(String)

The Turtle parser rejected the input.

TriG(String)

The TriG parser rejected the input.

RdfXml(String)

The RDF/XML parser rejected the input.

UnknownFormat(String)

The requested format is not one this crate can parse.

Rdf12TurtleUnavailable

QuotedTripleSurface::Rdf12 was asked for on a Turtle/TriG input, but this build of rete-core has the rdf12-turtle feature off, so the RDF 1.2 reader was not compiled in. Refused by name rather than read as RDF-star, which would be the wrong graph told in silence.

Io(String)

The input could not be read (streaming builds surface the path here).

InvalidIri

An IRI outside the N-Triples/N-Quads IRIREF grammar / RFC 3987, refused because the caller asked for a strict IriAudit (rete build --strict). Without strict the same finding is only counted. location is line N for the line-based syntaxes, the format name for the others (oxttl reports its own positions).

Fields

location: String

Where it was seen: line 42, or the format name.

token: String

The offending term token, verbatim.

reason: &'static str

Which rule it breaks (crate::iri::IriDefect::reason).

Trait Implementations

impl Debug for IngestError

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

Formats the value using the given formatter.

impl Display for IngestError

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

Formats the value using the given formatter.

impl Error for IngestError

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.
