Enum QueryStep 

pub enum QueryStep {
    Search {
        query: String,
        limit: usize,
    },
    VectorSearch {
        query: String,
        limit: usize,
    },

    },
    Filter(Predicate),
}

A single step in the query pipeline.

Variants

Search

Unified adaptive retrieval entry step consumed by the Phase 12 retrieval planner.

Carries the caller’s raw query string (not a parsed TextQuery): the planner decides how to interpret and route it across the text strict, text relaxed, and (future) vector branches. See crate::compile_retrieval_plan for the planner entry point.

Fields

query: String

The raw caller-supplied query string.

limit: usize

Maximum number of candidate rows requested by the caller.

VectorSearch

Nearest-neighbor search over vector embeddings.

Fields

query: String

The search query text (to be embedded by the caller).

limit: usize

Maximum number of candidate rows from the vector index.

TextSearch

Full-text search over indexed chunk content using FathomDB’s supported safe text-query subset.

Fields

query: TextQuery

Parsed text-search intent to be lowered into safe FTS5 syntax.

limit: usize

Maximum number of candidate rows from the FTS index.

Traverse

Graph traversal following edges of the given label.

Fields

direction: TraverseDirection

Direction to traverse.

label: String

Edge kind to follow.

max_depth: usize

Maximum hops from each candidate.

filter: Option<Predicate>

Optional predicate to filter traversal results. None is exactly equivalent to the pre-Pack-2 behavior. Some(_) is not yet implemented; see Pack 3.

Filter(Predicate)

Row-level filter predicate.

Trait Implementations

impl Clone for QueryStep

fn clone(&self) -> QueryStep

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryStep

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

Formats the value using the given formatter.

impl PartialEq for QueryStep

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