Expand description

Pluggable semantic similarity between two texts.

Implementations return a value in [0, 1] (1 = identical meaning). Embedding-based scorers can back this trait; the default LexicalScorer needs no model.

Required Methods§

Source

fn similarity<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, query: &'life1 str, document: &'life2 str, ) -> Pin<Box<dyn Future<Output = f64> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Similarity between query and document in [0, 1].

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
