Struct RetrievalBudget 

pub struct RetrievalBudget {
    pub lexical_ms: u64,
    pub semantic_ms: u64,
}

A time budget for a retrieval.

Fields

lexical_ms: u64

Milliseconds allowed for lexical search.

semantic_ms: u64

Milliseconds allowed for semantic fallback; zero disables it.

Implementations

impl RetrievalBudget

pub fn interactive() -> Self

The budget for a synchronous fallback on the tool-call path.

Semantic search gets a short deadline rather than none. It used to get none, on the reasoning that a network round trip would turn a slow answer into a late one — true of a remote backend, and the reason the deadline is short. But it also meant a local backend was never asked: measured against a perfect semantic oracle, this path answered exactly as many questions as BM25 alone, because the oracle was never once consulted. A deadline keeps the latency guarantee and stops throwing away the one path that could answer.

pub fn interactive_with(config: &RetrievalConfig) -> Self

The interactive budget under a specific configuration.

pub fn speculative() -> Self

The budget for speculative preparation, where semantic fallback is worth attempting because nothing is waiting on it.

pub fn speculative_with(config: &RetrievalConfig) -> Self

The speculative budget under a specific configuration.

Trait Implementations

impl Clone for RetrievalBudget

fn clone(&self) -> RetrievalBudget

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetrievalBudget

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

Formats the value using the given formatter.

impl PartialEq for RetrievalBudget

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