Struct ExpansionSlot 

pub struct ExpansionSlot {
    pub slot: String,
    pub direction: TraverseDirection,
    pub label: String,
    pub max_depth: usize,
    pub filter: Option<Predicate>,
    pub edge_filter: Option<Predicate>,
}

A named expansion slot that traverses edges per root result.

Fields

slot: String

Slot name used to key the expansion results.

direction: TraverseDirection

Direction to traverse edges.

label: String

Edge kind (label) to follow.

max_depth: usize

Maximum traversal depth.

filter: Option<Predicate>

Optional predicate to filter target nodes in this expansion slot. None is exactly equivalent to pre-Pack-2 behavior. Some(_) is not yet implemented; see Pack 3.

edge_filter: Option<Predicate>

Optional predicate to filter the traversed edges in this expansion slot. Only EdgePropertyEq and EdgePropertyCompare are valid here. None preserves pre-Pack-D behavior (no edge filtering).

Trait Implementations

impl Clone for ExpansionSlot

fn clone(&self) -> ExpansionSlot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpansionSlot

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

Formats the value using the given formatter.

impl PartialEq for ExpansionSlot

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