Enum EdgeKind 

pub enum EdgeKind {
    ForkOfParent,
}

Reserved-prefix edge kind for CapabilityQuery::traverse. Identifies which reserved-prefix tag forms a graph edge from a child entity to its parent.

Today’s substrate uses two reserved-prefix shapes that genuinely encode parent links:

• fork-of:<parent_origin_hex> — a forked entity carries a fork-of: tag whose body is the parent’s origin hash. The parent itself may carry its own fork-of: tag for the grand-parent. Walking these chains terminates at a root (an entity with no fork-of: tag).

• causal:<chain_hex> is NOT an edge kind in the parent-pointer sense — it’s a chain advertisement. Listed here so adding it later (e.g., for “find the chain head of chain X” traversal) is mechanical.

Variants

ForkOfParent

Walk fork-of:<parent> parent links upward.

Implementations

impl EdgeKind

pub fn prefix(&self) -> &'static str

Reserved-prefix string this edge kind walks. Matches the Tag::Reserved::prefix field for the corresponding tag.

Trait Implementations

impl Clone for EdgeKind

fn clone(&self) -> EdgeKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EdgeKind

impl Debug for EdgeKind

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

Formats the value using the given formatter.

impl Eq for EdgeKind

impl PartialEq for EdgeKind

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