Enum SoftFallbackBranch 

pub enum SoftFallbackBranch {
    Vector,
    Text,
    TextEdge,
    GraphArm,
}

Which retrieval branch produced a hit (or could not contribute).

Vector = ANN vector branch (node bodies); Text = node-body FTS branch; TextEdge = edge-body hit (FTS via search_index_edges OR vector-projected edge facts — both produce the same kind=“edge_fact” row shape and share the same downstream handling in search_expand_in_tx). Vector/Text also used as soft-fallback signal when the respective branch is empty. GraphArm = R3 (Slice 30) BFS-reachable node from the temporal fact-edge graph arm. Owned by dev/design/retrieval.md.

Variants

Vector

Text

TextEdge

G11 (Slice 15) — edge-body hit from search_index_edges FTS or from vector_default edge-fact projection. kind = "edge_fact" in both cases.

GraphArm

R3 (Slice 30) — BFS-reachable node from the temporal fact-edge graph arm. Only present when use_graph_arm = true. Nodes in the graph arm were NOT in the initial vector/text fused result (newly-reached nodes only).

Trait Implementations

impl Clone for SoftFallbackBranch

fn clone(&self) -> SoftFallbackBranch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SoftFallbackBranch

impl Debug for SoftFallbackBranch

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

Formats the value using the given formatter.

impl Eq for SoftFallbackBranch

impl PartialEq for SoftFallbackBranch

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