Enum RerankPolicy 

pub enum RerankPolicy {
    Auto,
    Always,
    Never,
}

Reranker firing policy for a search invocation.

Controls whether the cross-encoder reranker (TinyBERT-L-2-v2) runs after the bi-encoder retrieval step. Orthogonal to corpus selection — see Corpus for the corpus axis.

The Auto policy mirrors the pre-4.0 implicit behavior: rerank fires when the corpus is prose-heavy (≥ 30% of indexed chunks are prose) and the query is NL-shaped (not a symbol identifier).

Variants

Auto

Rerank fires when the corpus is prose-heavy and the query is NL-shaped. This was the pre-4.0 implicit default.

Always

Force rerank on regardless of corpus shape or query type.

Never

Skip rerank unconditionally — fastest path.

Trait Implementations

impl Clone for RerankPolicy

fn clone(&self) -> RerankPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RerankPolicy

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

Formats the value using the given formatter.

impl Default for RerankPolicy

fn default() -> RerankPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RerankPolicy

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RerankPolicy

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

impl Serialize for RerankPolicy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
