Expand description

Session state - conversation history and persistence

Fields§

§messages: Vec<ChatMessage>

Current chat messages

§conversation_manager: Option<ConversationManager>

Conversation manager for persistence

§current_conversation: Option<ConversationHistory>

Current conversation being tracked

§input_history: VecDeque<String>

Input history for arrow key navigation (loaded from session)

§history_index: Option<usize>

Current position in history (None = editing current input, Some(i) = viewing history[i])

§history_buffer: String

Saved input when navigating away from current draft

§context: Option<Context>

Context for dynamic file tree reloading

§cumulative_tokens: usize

Cumulative token count for the entire conversation

§conversation_title: Option<String>

Auto-generated conversation title (like Claude Code)

§markdown_cache: FxHashMap<(usize, usize), Vec<Line<'static>>>

Cached parsed markdown per message: (message_index, content_len) -> parsed lines Invalidated when content length changes (cheap proxy for content change)
