An error occurred while attempting to add an edge to the graph.

Variants

SrcNodeNotFound(NodeID)

The given source node was not found in the graph.

DstNodeNotFound(NodeID)

The given destination node was not found in the graph.

InPortOutOfRange

The given input port index is out of range.

Fields

node: NodeID

port_idx: InPortIdx

num_in_ports: u32

OutPortOutOfRange

The given output port index is out of range.

Fields

node: NodeID

port_idx: OutPortIdx

num_out_ports: u32

EdgeAlreadyExists

The edge already exists in the graph.

InputPortAlreadyConnected(NodeID, InPortIdx)

The input port is already connected.

CycleDetected

This edge would have created a cycle in the graph.

Trait Implementations

impl Clone for AddEdgeError

fn clone(&self) -> AddEdgeError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AddEdgeError

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

Formats the value using the given formatter.

impl Display for AddEdgeError

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

Formats the value using the given formatter.

impl Error for AddEdgeError

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.
