Enum GraphError 

pub enum GraphError {
    DanglingValue(ValueId),
    DanglingNode(NodeId),
    CycleDetected,
    MissingProducer(ValueId),
    DuplicateOutput(ValueId),
    InputHasProducer(ValueId),
    ProducerLinkMismatch(ValueId),
    ConsumerLinkMismatch(ValueId),
    InvalidOpsetImport {
        domain: String,
        version: u64,
    },
}

A single structural defect in a Graph.

Variants

DanglingValue(ValueId)

A node references a value id that is not live in the value arena.

DanglingNode(NodeId)

A referenced node id is not live in the node arena.

CycleDetected

The graph contains a cycle (no valid topological order).

MissingProducer(ValueId)

A graph output (or interior value) has no producing node.

DuplicateOutput(ValueId)

The same value is produced as an output more than once (SSA violation).

InputHasProducer(ValueId)

A graph input has a producer node (inputs must be sources).

ProducerLinkMismatch(ValueId)

A value’s producer link disagrees with the node’s outputs.

ConsumerLinkMismatch(ValueId)

A value’s consumer-use set disagrees with a node’s inputs.

InvalidOpsetImport

An opset import is malformed.

Fields

domain: String

version: u64

Trait Implementations

impl Clone for GraphError

fn clone(&self) -> GraphError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphError

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

Formats the value using the given formatter.

impl Display for GraphError

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

Formats the value using the given formatter.

impl Eq for GraphError

impl Error for GraphError

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 GraphError

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

Equality operator ==.

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

Inequality operator !=.
