All messages in the conversation history.

Implementations

impl ChatState

pub fn new() -> Self

Create a new empty chat state.

pub fn handle_update(&mut self, update: SessionUpdate)

Process an incoming SessionUpdate from the agent, updating chat state accordingly.

Non-chunk updates automatically flush any accumulated agent text buffer so that the complete message is recorded before tool calls or other events.

pub fn flush_agent_message(&mut self)

Flush the agent text buffer into a completed ChatMessage::Agent message and reset streaming state.

Also extracts any fenced bash/sh code blocks and appends them as ChatMessage::CommandSuggestion entries so the UI can offer “Run in terminal” buttons.

pub fn streaming_text(&self) -> &str

Returns the current in-progress streaming text (not yet flushed).

pub fn add_user_message(&mut self, text: String)

Add a user message to the conversation.

Flushes any pending agent text first so messages stay interleaved.

pub fn add_system_message(&mut self, text: String)

Add a system message to the conversation.

pub fn add_command_suggestion(&mut self, command: String)

Add a command suggestion to the conversation.

pub fn add_auto_approved(&mut self, description: String)

Add an auto-approved tool call notice to the conversation.
