Struct EdgeAt 

pub struct EdgeAt {
    pub edge_type: String,
    pub src_key: String,
    pub dst_key: String,
    pub derived: bool,
    pub rule: Option<String>,
}

One directed edge incident on a node at a point in WAL history, with the rule that derived it when it is rule-owned.

Returned by GraphDb::edges_at (sorted by (edge_type, src_key, dst_key)) and by GraphDb::what_if_set_prop.

Fields

edge_type: String

src_key: String

dst_key: String

derived: bool

true when a rule wrote the edge (DerivedEdgeAdded in the WAL, or a live provenance entry).

rule: Option<String>

The rule that derived the edge. None for a manual edge.

Trait Implementations

impl Clone for EdgeAt

fn clone(&self) -> EdgeAt

impl Eq for EdgeAt

impl Ord for EdgeAt

fn cmp(&self, other: &EdgeAt) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for EdgeAt

fn eq(&self, other: &EdgeAt) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for EdgeAt

fn partial_cmp(&self, other: &EdgeAt) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool
