Trait Implementations

impl<'a, E, Ix: IndexType> Clone for EdgeReference<'a, E, Ix>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, E: Debug, Ix: Debug + IndexType> Debug for EdgeReference<'a, E, Ix>

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

Formats the value using the given formatter.

impl<'a, E, Ix: IndexType> EdgeRef for EdgeReference<'a, E, Ix>

type NodeId = NodeIndex<Ix>

type EdgeId = EdgeIndex<Ix>

type Weight = E

fn source(&self) -> Self::NodeId

The source node of the edge.

fn target(&self) -> Self::NodeId

The target node of the edge.

fn id(&self) -> Self::EdgeId

The edge’s identifier.

fn weight(&self) -> &Self::Weight

A reference to the weight of the edge.

impl<'a, E: Ord, Ix: Ord + IndexType> Ord for EdgeReference<'a, E, Ix>

fn cmp(&self, other: &EdgeReference<'a, E, Ix>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl<'a, E: PartialEq, Ix: PartialEq + IndexType> PartialEq<EdgeReference<'a, E, Ix>> for EdgeReference<'a, E, Ix>

fn eq(&self, other: &EdgeReference<'a, E, Ix>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &EdgeReference<'a, E, Ix>) -> bool

This method tests for !=.

impl<'a, E: PartialOrd, Ix: PartialOrd + IndexType> PartialOrd<EdgeReference<'a, E, Ix>> for EdgeReference<'a, E, Ix>

fn partial_cmp(&self, other: &EdgeReference<'a, E, Ix>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
