Enum TopoError 

pub enum TopoError {
    CycleDetected(Vec<TopoNodeId>),
    NodeNotFound(TopoNodeId),
    EmptyGraph,
}

Error types for topological sort operations.

Variants

CycleDetected(Vec<TopoNodeId>)

The graph contains a cycle, making topological sort impossible.

Tuple Fields

0: Vec<TopoNodeId>

Nodes involved in the cycle.

NodeNotFound(TopoNodeId)

A referenced node does not exist in the graph.

Tuple Fields

0: TopoNodeId

The missing node.

EmptyGraph

The graph is empty.

Trait Implementations

impl Clone for TopoError

fn clone(&self) -> TopoError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TopoError

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

Formats the value using the given formatter.

impl Display for TopoError

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

Formats the value using the given formatter.

impl Eq for TopoError

impl PartialEq for TopoError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
