Functions§
- append_
assistant_ text_ part - Append a streamed text part to the running assistant text, inserting the right number of blank lines so consecutive parts don’t glue together.
- build_
prompt - build_
tool_ surface - build_
turn - default_
prompt_ template - head_
tail_ truncate - messages_
are_ prompt_ resume_ safe - normalized_
response_ parts - Convert a raw
LlmResponseinto a stream ofLlmOutputParts that downstream code can iterate. When the response only carriesfull_text(provider didn’t populateparts), synthesize a singleTextpart. - prompt_
template_ fingerprint - prompt_
text_ fingerprint - prompt_
tool_ names_ fingerprint - reasoning_
part - Build a Reasoning
Partfrom a reasoning item.metais Some when the item carries provider replay metadata; None for display-only summaries. - render_
turn_ causes_ prompt - resolve_
prompt_ layers - shared_
parts - Wrap a
Vec<Part>for theMessage::partsfield. Use this in struct literals and tests (parts: shared_parts(vec![Part { ... }])) so the call sites stay short and uniform. - validate_
tool_ input
Type Aliases§
- Base
Render Cache - Memoized render of a
MessageSequence’sbase. Shared across the per-iterationMessageSequenceinstances that wrap the same base (typically theSessionGraphCache’s projected messages) so the chat projector’srender_promptwalk happens once per turn instead of once per LLM iteration. - Driver
Action - Driver
Context View - Effect
- Prepared
Turn Machine - Progress
Sender - Sender for streaming progress messages from tools (e.g. live bash output).
