Struct NoopEmbedder 

pub struct NoopEmbedder {
    dimension: usize,
    modalities: Vec<Modality>,
}

No-op embedder that returns zero-vectors.

This embedder is always available, even without the candle feature. It returns 384-dimensional zero-vectors for all inputs, making it useful for testing and development.

Example

use ragfs_embed::NoopEmbedder;
use ragfs_core::{Embedder, EmbeddingConfig};

let embedder = NoopEmbedder::new();
let config = EmbeddingConfig::default();
let texts: Vec<&str> = vec!["Hello", "World"];
let outputs = embedder.embed_text(&texts, &config).await?;

assert_eq!(outputs.len(), 2);
assert_eq!(outputs[0].embedding.len(), 384);
assert!(outputs[0].embedding.iter().all(|&v| v == 0.0));

Fields

dimension: usize

modalities: Vec<Modality>
