Enum RootChoice 

pub enum RootChoice {
    Degree,
    Eccentricity,
}

Heuristic for selecting tree-layout roots when multiple candidates exist within a component.

Variants

Degree

Pick the vertex with the highest degree (out- or in-degree for directed graphs). Fast — O(n) after sorting.

Eccentricity

Pick the vertex with the lowest eccentricity (“most central”). Produces wide, shallow layouts. Slow — O(n²) eccentricity BFS.

Trait Implementations

impl Clone for RootChoice

fn clone(&self) -> RootChoice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RootChoice

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

Formats the value using the given formatter.

impl PartialEq for RootChoice

fn eq(&self, other: &RootChoice) -> 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.
