Struct PromptedTextEmbedder 

pub struct PromptedTextEmbedder<E> { /* private fields */ }

Wrapper that applies a PromptTemplate before calling an inner TextEmbedder.

This is the “instruction/scoped embedding” adapter when a backend:

• ignores EmbedMode, or
• expects explicit prompt prefixes.

Nuance: If your inner backend already applies its own prompt logic (e.g. a backend that uses EmbedMode internally), wrapping may double-prefix. Keep this opt-in.

Implementations

pub fn new(inner: E, prompt: PromptTemplate) -> Self

pub fn prompt(&self) -> &PromptTemplate

pub fn into_inner(self) -> E

Trait Implementations

impl<E: Clone> Clone for PromptedTextEmbedder<E>

fn clone(&self) -> PromptedTextEmbedder<E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for PromptedTextEmbedder<E>

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

Formats the value using the given formatter.

impl<E: TextEmbedder> TextEmbedder for PromptedTextEmbedder<E>

fn embed_texts( &self, texts: &[String], mode: EmbedMode, ) -> Result<Vec<Vec<f32>>>

Embed texts into vectors.

fn model_id(&self) -> Option<&str>

Optional: model identifier for debugging and provenance.

fn dimension(&self) -> Option<usize>

Optional: embedding dimension as returned by this embedder.

fn capabilities(&self) -> TextEmbedderCapabilities

Optional: backend capability declaration.

fn embed_text(&self, text: &str, mode: EmbedMode) -> Result<Vec<f32>>

Convenience: embed a single text, avoiding the &[s.to_string()][0].clone() boilerplate.
