}

Errors that can occur when constructing or validating IR.

Variants

UnknownEdge

An edge referenced by a graph node was not registered.

Fields

edge_id: u32

node_name: String

DuplicateEdgeProducer

An output edge already has a producer node.

Fields

edge_id: u32

existing_producer: String

new_producer: String

CycleDetected

A cycle was detected in the computation graph.

Fields

visited: usize

total: usize

Trait Implementations

impl Debug for IrError

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

Formats the value using the given formatter.

impl Display for IrError

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

Formats the value using the given formatter.

impl Error for IrError

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.
