Struct TextRenderer 

pub struct TextRenderer { /* private fields */ }

Stateful text-mode renderer.

Tracks the latest assistant message observed across the whole stream so that multiple prompts, retries, and compaction rounds collapse to a single final answer. No output is produced until finish; intermediate streaming events only update internal state.

Implementations

impl TextRenderer

pub fn new() -> Self

Create an empty renderer.

pub fn handle(&mut self, event: &AgentSessionEvent)

Observe one event.

Every AgentSessionEvent variant is handled. Authoritative assistant snapshots come from turn-end, message-end, message-update, and agent-end so fragmented streaming and multi-turn runs coalesce into a single final answer. Other variants are consumed without side effects so the renderer never panics on thinking, tool, compaction, retry, or queue events.

pub fn last_assistant(&self) -> Option<&AssistantMessage>

Borrow the tracked final assistant message, if any.

pub async fn finish<K>(&self, sink: &K) -> Result<i32>

where K: PrintSink,

Emit the final text (or error) and return the exit code.

Errors

Propagates sink write failures.

Trait Implementations

impl Default for TextRenderer

fn default() -> TextRenderer
