Enum AcyclicEdgeError

pub enum AcyclicEdgeError<N> {
    Cycle(Cycle<N>),
    SelfLoop,
    InvalidEdge,
}

An error that can occur during edge addition for acyclic graphs.

Variants

Cycle(Cycle<N>)

The edge would create a cycle.

SelfLoop

The edge would create a self-loop.

InvalidEdge

Could not successfully add the edge to the underlying graph.

Trait Implementations

impl<N: Clone> Clone for AcyclicEdgeError<N>

fn clone(&self) -> AcyclicEdgeError<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N: Debug> Debug for AcyclicEdgeError<N>

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

Formats the value using the given formatter.

impl<N> From<Cycle<N>> for AcyclicEdgeError<N>

fn from(cycle: Cycle<N>) -> Self

Converts to this type from the input type.

impl<N: PartialEq> PartialEq for AcyclicEdgeError<N>

fn eq(&self, other: &AcyclicEdgeError<N>) -> 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.
