Enum Error 

pub enum Error {
    Cardinality(CardinalityError),
    Syntax(SyntaxError),
}

The error type for this crate.

Variants

Cardinality(CardinalityError)

An error caused by a clause appearing an invalid number of times.

For instance, OBO frames have union_of clauses, that can not appear only once: they must appear zero, or more than two times. Having a frame with a single union_of clause will error when attempting to translate the whole document.

Example:

use fastobo_owl::IntoOwl;
use fastobo_owl::IntoOwlPrefixes;

let mut frame = TermFrame::new(ClassIdent::from(PrefixedIdent::new("TST", "001")));
let id = Box::new(ClassIdent::from(PrefixedIdent::new("TST", "002")));
frame.push(Line::from(TermClause::UnionOf(id)));

let doc = OboDoc::with_entities(vec![EntityFrame::from(frame)]);
let res = doc.into_owl::<SetOntology<String>>();
assert!(matches!(res, Err(fastobo_owl::Error::Cardinality(_))));

Syntax(SyntaxError)

An error caused by an element in invalid syntax.

This can be raised while building IRI and Version IRI for an OWL ontology from an OBO ontology header clause, which may contain invalid data.

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<CardinalityError> for Error

fn from(source: CardinalityError) -> Self

Converts to this type from the input type.

impl From<SyntaxError> for Error

fn from(source: SyntaxError) -> Self

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
