Enum ReferenceResolutionError 

pub enum ReferenceResolutionError {
    UndeclaredIndexSet {
        name: String,
        index: String,
        node: String,
        model: String,
        path: String,
    },
    UnknownFaqNode {
        index_set: String,
        from_faq: String,
        model: String,
    },
    DuplicateNodeId {
        id: String,
        model: String,
        path: String,
        first: String,
    },
    UnresolvedJoinFactor {
        factor: String,
        node: String,
        model: String,
        path: String,
    },
    ReferenceCycle {
        path: Vec<String>,
    },
}

A reference could not be resolved, or the reference graph has a cycle.

Variant names are deliberately cross-language-compatible so the Julia, Python, and Rust bindings report the same failure mode under the same name (mirrors the E_REF_* codes in the Python binding).

Variants

UndeclaredIndexSet

A ranges[*].from names an index set not declared in index_sets.

Fields

name: String

index: String

node: String

model: String

path: String

UnknownFaqNode

A kind:"derived" index set’s from_faq names no expression-node id.

Resolved at DOCUMENT scope (esm-spec.md §9.7.5); model names the model whose graph was being built when the lookup failed.

Fields

index_set: String

from_faq: String

model: String

DuplicateNodeId

Two expression nodes in the same DOCUMENT share an explicit id.

Node ids are unique per document, not per model (esm-spec.md §9.7.5); when the two occurrences are in different models the paths are model-qualified and model names the second occurrence’s model.

Fields

id: String

model: String

path: String

first: String

UnresolvedJoinFactor

A join.on factor reference names nothing in the node’s scope.

Fields

factor: String

node: String

model: String

path: String

ReferenceCycle

A directed cycle exists among the reference edges (RFC §6.1 acyclicity).

Fields

path: Vec<String>

Trait Implementations

impl Clone for ReferenceResolutionError

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 ReferenceResolutionError

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

impl Eq for ReferenceResolutionError

impl Error for ReferenceResolutionError

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 ReferenceResolutionError

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

Equality operator ==.

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

Inequality operator !=.
