Enum LlmStreamEvent

    RetryStatus {

Variants

AttemptReset

A retry is starting from the original request. Consumers must discard attempt-local accumulated parts and usage before accepting new events.

Delta(String)

Append-only visible assistant text. Providers must send only the new suffix here; completed/cumulative message text belongs in Part(Text).

ReasoningDelta(String)

Incremental reasoning-summary text. Kept separate from Delta so the UI can render it in a distinct muted/italic style rather than mixing it into the assistant’s final text.

Part(LlmOutputPart)

Structured provider output state. Text parts reconcile final response state and replay metadata; they are not live-visible text deltas.

Usage(LlmUsage)

RetryStatus

Fields

wait_seconds: u64

attempt: usize

max_attempts: usize
