Enum ToUndirectedMode 

pub enum ToUndirectedMode {
    Each,
    Collapse,
    Mutual,
}

Mode for converting a directed graph to undirected.

Variants

Each

Each directed edge becomes an undirected edge. Parallel directed edges (same direction) become parallel undirected edges.

Collapse

Collapse mutual edges: if both (u,v) and (v,u) exist, produce one undirected edge. Non-mutual directed edges are also kept as one undirected edge.

Mutual

Keep only mutual edges: an undirected edge (u,v) is produced only if both (u,v) and (v,u) exist in the directed graph.

Trait Implementations

impl Clone for ToUndirectedMode

fn clone(&self) -> ToUndirectedMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToUndirectedMode

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

Formats the value using the given formatter.

impl PartialEq for ToUndirectedMode

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