Struct RecallParams 

pub struct RecallParams<'a> {
    pub query: &'a str,
    pub budget: usize,
    pub trace: bool,
    pub include_sparks: bool,
    pub top: Option<usize>,
    pub source: &'a str,
    pub expand_deps: &'a str,
    pub allow_trim: bool,
    pub refine_mode: &'a str,
    pub min_score: Option<f64>,
    pub session_only: bool,
    pub rerank: bool,
}

Parameters for KnowledgeBase::recall.

Borrowed, Default-able: construct with RecallParams { query, budget, source, ..Default::default() }. Empty-string defaults are normalized inside recall: expand_deps empty → "false", refine_mode empty → "off".

Fields

query: &'a str

budget: usize

trace: bool

include_sparks: bool

top: Option<usize>

source: &'a str

expand_deps: &'a str

allow_trim: bool

refine_mode: &'a str

min_score: Option<f64>

Relevance gate: drop candidates whose fused score is below this value before packing/trace, so the trace only records knowledge that was actually surfaced. None disables the gate. Used by always-on hooks (UserPromptSubmit / SessionStart) to stay high-frequency without noise.

session_only: bool

Session trace mode: open an episodic log for later record-correlation but write no per-chunk retrieved/selected usage events. Used by the daemon, which recalls only to obtain a trace_id and discards the knowledge without ever placing it in a model context. selected must strictly mean “entered the model context”, so a caller that does not inject the result must set this. Defaults to false (full injection).

rerank: bool

Part (d) — opt-in offline LLM rerank of the candidate shortlist. Off by default so the hot hook path stays no-LLM; only set it in latency-tolerant callers (“deep recall”). No-op unless a reranker was injected (LLM configured), and non-fatal: a reranker error falls back to the fused order.

Trait Implementations

impl<'a> Clone for RecallParams<'a>

fn clone(&self) -> RecallParams<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for RecallParams<'a>

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

Formats the value using the given formatter.

impl<'a> Default for RecallParams<'a>

fn default() -> RecallParams<'a>

Returns the “default value” for a type.
