Enum SimpleMode 

pub enum SimpleMode {
    DirectedAsDirected,
    DirectedAsUndirected,
}

Direction-handling for is_simple_with_mode. Counterpart of upstream’s directed boolean parameter.

On undirected graphs both modes produce the same answer.

Variants

DirectedAsDirected

(a, b) and (b, a) are distinct directed edges. Default; matches what plain is_simple returns.

DirectedAsUndirected

(a, b) and (b, a) collapse to the same undirected edge, so a mutual pair is reported as a multi-edge.

Trait Implementations

impl Clone for SimpleMode

fn clone(&self) -> SimpleMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SimpleMode

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

Formats the value using the given formatter.

impl PartialEq for SimpleMode

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