Module reliability 

Reliability primitives: circuit breaker, instrumented model wrappers with timeout and retry support, and metrics emission.

Structs

CircuitBreakerConfig

Tunable parameters for the circuit breaker.

CircuitBreakerWrapper

Thread-safe circuit breaker that tracks failures and short-circuits calls when a provider is unhealthy.

InstrumentedAudioEmbeddingModel

Wrapper around an AudioEmbeddingModel adding timeout / retry / metrics.

InstrumentedDocumentExtractionModel

Wrapper around a DocumentExtractionModel adding timeout / retry / metrics.

InstrumentedEmbeddingModel

Wrapper around an EmbeddingModel that adds per-call timeout enforcement, exponential-backoff retries for transient errors, and metrics emission (model_inference.duration_seconds, model_inference.total).

InstrumentedGeneratorModel

Wrapper around a GeneratorModel that adds timeout, retry, and metrics.

InstrumentedHybridEmbeddingModel

Wrapper around a HybridEmbeddingModel adding timeout / retry / metrics.

InstrumentedImageEmbeddingModel

Wrapper around an ImageEmbeddingModel adding timeout / retry / metrics.

InstrumentedMultiVectorEmbeddingModel

Wrapper around a MultiVectorEmbeddingModel adding timeout / retry / metrics.

InstrumentedMultimodalEmbeddingModel

Wrapper around a MultimodalEmbeddingModel adding timeout / retry / metrics.

InstrumentedNlpModel

Wrapper around an NlpModel adding timeout / retry / metrics.

InstrumentedOcrModel

Wrapper around an OcrModel adding timeout / retry / metrics.

InstrumentedRawTensorModel

Wrapper around an RawTensorModel that adds timeout, retry, and metrics.

InstrumentedRerankerModel

Wrapper around a RerankerModel that adds timeout, retry, and metrics.

InstrumentedSparseEmbeddingModel

Wrapper around a SparseEmbeddingModel adding timeout / retry / metrics.

InstrumentedTranscriptionModel

Wrapper around a TranscriptionModel adding timeout / retry / metrics to the batch transcribe call.
