Module streaming 

Streaming response codecs for the managed LLM execution pipeline.

crate::codec::traits::LlmResponseCodec decodes a complete provider response into a normalized AnnotatedLlmResponse. For streaming providers, the analogous job is to:

1. consume per-chunk events as they arrive on a streaming HTTP response, and
2. assemble a single non-streaming-shape JSON payload at end of stream.

Once assembled, the payload can be fed back through the matching crate::codec::traits::LlmResponseCodec to produce an AnnotatedLlmResponse — meaning streaming and non-streaming requests converge on the same observability output without per-route shape duplication.

StreamingCodec is the trait that bundles the two functions (LlmCollectorFn, LlmFinalizerFn) used by crate::api::llm::llm_stream_call_execute. Each provider supplies one impl whose internal state holds whatever incremental information is needed to materialize the final payload.

Structs

SseEvent

One decoded SSE frame, paired with the parsed data: payload.

SseEventDecoder

Incremental decoder for text/event-stream byte streams that yields one JSON object per complete data: payload.

Enums

NormalizedStreamEvent

Provider-neutral incremental stream item used by cross-protocol transcoders.

Traits

StreamingCodec

Per-provider streaming codec used with crate::api::llm::llm_stream_call_execute.
