Struct FnCrossEncoder 

pub struct FnCrossEncoder<F>
where
    F: Fn(&str, &Document) -> f32 + Send + Sync,
{
    pub f: F,
}

Closure-backed cross-encoder. Useful for tests; in production use a real impl that calls a hosted scorer.

Fields

f: F

Per-doc scorer; runs concurrently across docs.

Trait Implementations

impl<F> CrossEncoder for FnCrossEncoder<F>

where F: Fn(&str, &Document) -> f32 + Send + Sync,

fn score<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, query: &'life1 str, docs: &'life2 [Document], ) -> Pin<Box<dyn Future<Output = Result<Vec<f32>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Score every doc against query. Higher = more relevant. Implementations should batch when possible.
