Enum BindingError 

pub enum BindingError {
    UnknownConcept {
        kind: ConceptKind,
        concept: String,
    },
    UndeclaredTypeSystem(SourceId),
    Unbound {
        kind: ConceptKind,
        concept: String,
        type_systems: Vec<String>,
    },
    Ambiguous {
        kind: ConceptKind,
        concept: String,
        names: Vec<String>,
    },
}

Why a concept could not be bound for one source.

Variants

UnknownConcept

The concept is not declared by any loaded definition package.

Fields

kind: ConceptKind

Catalog the concept was looked up in.

concept: String

Concept identifier.

UndeclaredTypeSystem(SourceId)

The source declares no type system, so no concept can bind to it.

Unbound

The concept has no name in any type system the source declared.

Fields

kind: ConceptKind

Catalog the concept belongs to.

concept: String

Concept identifier.

type_systems: Vec<String>

Type systems the source declared.

Ambiguous

The concept has different names in several declared type systems.

Picking one would decide which vocabulary the source “really” uses, which only the source can say, so the binding is refused.

Fields

kind: ConceptKind

Catalog the concept belongs to.

concept: String

Concept identifier.

names: Vec<String>

Distinct candidate names, sorted.

Trait Implementations

impl Clone for BindingError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BindingError

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

Formats the value using the given formatter.

impl Display for BindingError

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

Formats the value using the given formatter.

impl Eq for BindingError

impl Error for BindingError

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 BindingError

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

Equality operator ==.

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

Inequality operator !=.
