Enum MembershipMode 

pub enum MembershipMode {
    InQueue,
    Visited,
}

Controls how membership is tracked when popping values.

Variants

InQueue

Membership is cleared upon popping, allowing the value to be enqueued again.

Visited

Membership persists after popping, preventing re-enqueueing.

Trait Implementations

impl Clone for MembershipMode

fn clone(&self) -> MembershipMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MembershipMode

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

Formats the value using the given formatter.

impl PartialEq for MembershipMode

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