Struct SimEmbeddingProvider 

pub struct SimEmbeddingProvider { /* private fields */ }

In-memory embedding provider for deterministic simulation testing.

Features:

• Deterministic: same text + same seed = same embedding
• No external dependencies
• Fast (no network calls)
• Normalized embeddings (unit vectors)
• Fault injection support for DST

Implementations

impl SimEmbeddingProvider

pub fn new(seed: u64) -> Self

Create a new simulated embedding provider with the given seed.

Arguments

• seed - Base seed for deterministic generation

Example

use umi_memory::embedding::SimEmbeddingProvider;

let provider = SimEmbeddingProvider::new(42);

pub fn with_seed(seed: u64) -> Self

Create with explicit seed (alias for new).

pub fn with_faults(seed: u64, fault_injector: Arc<FaultInjector>) -> Self

Create with fault injection enabled.

Trait Implementations

impl Clone for SimEmbeddingProvider

fn clone(&self) -> SimEmbeddingProvider

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl EmbeddingProvider for SimEmbeddingProvider

fn embed<'life0, 'life1, 'async_trait>( &'life0 self, text: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<f32>, EmbeddingError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Generate embedding for a single text.

fn embed_batch<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, texts: &'life1 [&'life2 str], ) -> Pin<Box<dyn Future<Output = Result<Vec<Vec<f32>>, EmbeddingError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Generate embeddings for multiple texts (batch).

fn dimensions(&self) -> usize

Get the embedding dimensions (e.g., 1536 for text-embedding-3-small).

fn name(&self) -> &'static str

Provider name for logging and debugging.

fn is_simulation(&self) -> bool

Check if this is a simulation provider.
