Enum ConstructError 

pub enum ConstructError {
    UnboundVariable {
        name: String,
    },
    EmptyTerm {
        position: &'static str,
    },
    BlankNodeInPredicate {
        node: String,
    },
}

Errors that can occur during CONSTRUCT processing.

Variants

UnboundVariable

A variable used in the template was not found in the solution.

Fields

name: String

EmptyTerm

A triple term (subject, predicate, or object) was empty.

Fields

position: &'static str

BlankNodeInPredicate

Predicate position contained a blank node (SPARQL prohibits this).

Fields

node: String

Trait Implementations

impl Clone for ConstructError

fn clone(&self) -> ConstructError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConstructError

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

Formats the value using the given formatter.

impl Display for ConstructError

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

Formats the value using the given formatter.

impl Eq for ConstructError

impl Error for ConstructError

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 PartialEq for ConstructError

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

Equality operator ==.

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

Inequality operator !=.
