Struct InMemoryBackend 

pub struct InMemoryBackend { /* private fields */ }

In-memory embedding backend for unit tests.

Returns a deterministic f32 blob for any input. The blob contains dimensions floats, each set to 0.1. Tracks call count for assertions.

Implementations

impl InMemoryBackend

pub fn new(dimensions: usize) -> Self

Create a backend that returns vectors of the given dimensionality.

pub fn call_count(&self) -> usize

Number of times embed has been called.

Trait Implementations

impl EmbeddingBackend for InMemoryBackend

fn embed( &self, _input: &str, ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>>> + Send + '_>>

Embed a single text string.

fn dimensions(&self) -> usize

Number of dimensions this provider/model produces.

fn model_name(&self) -> &str

Model identifier string (e.g. "text-embedding-3-small").
