Enum LineageDirection 

pub enum LineageDirection {
    Back,
    Forward,
}

Direction of a OperatorPlan::LineageEmit walk.

Variants

Back

Walk fork-of: parents toward ancestors. The CapabilityIndex answer is direct: each chain’s fork-of:<parent_hash> tag names its parent.

Forward

Walk fork-of: descendants. Scans every entry in the capability index for a fork-of:<this_origin> tag, BFS-style, sorted by chain hash for determinism.

Trait Implementations

impl Clone for LineageDirection

fn clone(&self) -> LineageDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LineageDirection

impl Debug for LineageDirection

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LineageDirection

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for LineageDirection

impl PartialEq for LineageDirection

fn eq(&self, other: &LineageDirection) -> 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 LineageDirection

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
