impl<Ix: Ord> Ord for NodeIndex<Ix>

fn cmp(&self, other: &NodeIndex<Ix>) -> Ordering

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<Ix: PartialEq> PartialEq for NodeIndex<Ix>

fn eq(&self, other: &NodeIndex<Ix>) -> bool

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

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

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