Error raised while deserializing a value from Linked Data.

Variants

ExpectedIri(ContextIris)

Resource has no IRI representation.

UnsupportedIri

Resource is identified by an IRI the type does not accept.

Fields

context: ContextIris

Error context.

found: IriBuf

Unsupported IRI.

supported: Option<Vec<IriBuf>>

Optional hint listing the supported IRIs.

ExpectedLiteral(ContextIris)

Resource has no literal representation.

LiteralTypeMismatch

Resource has literal representations, but none of the expected type.

The type IRIs are boxed: this is the only variant carrying two of them, and inline they would make it the largest variant by a wide margin, which sets the size of the whole enum.

Fields

context: ContextIris

Error context.

expected: Option<Box<IriBuf>>

Expected literal type, if the type accepts only one.

found: Box<IriBuf>

Literal type actually found.

InvalidLiteral(ContextIris)

Resource has a literal representation of the correct type, but the lexical value could not be successfully parsed.

MissingRequiredValue(ContextIris)

Missing required value.

TooManyValues(ContextIris)

Too many values.

InvalidSubject

Generic error for invalid subjects.

Fields

context: ContextIris

Error context.

subject: Option<IriBuf>

Subject IRI, if it has one.

Implementations

impl FromLinkedDataError

pub fn context(&self) -> &ContextIris

Returns the context in which this error was raised.

Trait Implementations

impl Debug for FromLinkedDataError

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

Formats the value using the given formatter.

impl Display for FromLinkedDataError

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

Formats the value using the given formatter.

impl Error for FromLinkedDataError

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>)
