Enum PathSupport 

pub enum PathSupport {
    Empty,
    Edge(Triple),
    Chain(Vec<PathSupport>),
    Alt(Vec<PathSupport>),
}

The existing triples that make a node a π-successor of its parent: the edges a deletion would cut. The deletion-side dual of path materialization.

Variants

Empty

Reflexive (Id): the node reached itself; nothing to cut.

Edge(Triple)

A single triple edge whose removal breaks this step.

Chain(Vec<PathSupport>)

A chain (Seq/Star expansion): every edge present; cut any one to break.

Alt(Vec<PathSupport>)

Parallel witnessing chains (Alt): cut all to break.

Trait Implementations

impl Clone for PathSupport

fn clone(&self) -> PathSupport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PathSupport

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PathSupport

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PathSupport

impl PartialEq for PathSupport

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

impl Serialize for PathSupport

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
