Enum petgraph::Direction

#[repr(usize)]
pub enum Direction {
    Outgoing,
    Incoming,
}

Edge direction.

Variants

Outgoing

An Outgoing edge is an outward edge from the current node.

Incoming

An Incoming edge is an inbound edge to the current node.

Implementations

impl Direction

pub fn opposite(&self) -> Direction

Return the opposite Direction.

pub fn index(&self) -> usize

Return 0 for Outgoing and 1 for Incoming.

Trait Implementations

impl Clone for Direction

fn clone(&self) -> Self

Returns a copy of the value.

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

impl Ord for Direction

fn cmp(&self, other: &Direction) -> Ordering

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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