Enum IngestError 

pub enum IngestError {
    BnodeCycle {
        labels: Vec<String>,
    },
    Io(String),
}

Error returned by ingest_ntriples when the input cannot be completed without compromising semantics.

Variants

BnodeCycle

A blank-node cycle was detected. Each label’s intrinsic id depends on its neighbors’ ids, so a cycle has no fixed-point assignment without a more elaborate symmetry-breaking scheme (see RDF-Canon’s gossip-path algorithm). We refuse rather than emit something arbitrary.

Fields

labels: Vec<String>

The bnode labels that participate in the unresolved cycle.

Io(String)

The underlying reader returned an I/O error.

Trait Implementations

impl Clone for IngestError

fn clone(&self) -> IngestError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IngestError

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

Formats the value using the given formatter.

impl Display for IngestError

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

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>)
