Struct PlaceholderEmbedder 

pub struct PlaceholderEmbedder;

Deterministic low-dimensional embedding for tests and offline M3 development. Maps text to a L2-normalized PLACEHOLDER_EMBED_DIM-vector from a 64-bit hash of the string — not semantically meaningful; cosine ranks correlate weakly with lexical overlap.

Implementations

impl PlaceholderEmbedder

pub const fn new() -> Self

Create a new deterministic hasher-based embedder (L2-normalized, fixed dimension).

Trait Implementations

impl Clone for PlaceholderEmbedder

fn clone(&self) -> PlaceholderEmbedder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlaceholderEmbedder

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

Formats the value using the given formatter.

impl Default for PlaceholderEmbedder

fn default() -> PlaceholderEmbedder

Returns the “default value” for a type.

impl Embedder for PlaceholderEmbedder

fn embed(&self, text: &str) -> Result<Vec<f32>, EmbedderError>

Embed a single text. Returns a fixed-dimension vector.

fn embed_batch(&self, texts: &[&str]) -> Result<Vec<Vec<f32>>, EmbedderError>

Embed a batch (default impl loops; backends should override for efficiency).

impl Copy for PlaceholderEmbedder
