Trait ChartAppState 

pub trait ChartAppState {
    // Required methods
    fn active_symbol(&self) -> &str;
    fn active_timeframe(&self) -> &Timeframe;
    fn chart_type(&self) -> ChartType;
    fn is_connected(&self) -> bool;
    fn is_replay_active(&self) -> bool;
}

Trait for application state that chart UI components can read from.

Library consumers implement this on their app state type to connect the UI components to their data layer.

Required Methods

fn active_symbol(&self) -> &str

Currently active trading symbol (e.g., “AAPL”, “BTC/USD”).

fn active_timeframe(&self) -> &Timeframe

Current chart timeframe.

fn chart_type(&self) -> ChartType

Current chart visualization type.

fn is_connected(&self) -> bool

Whether the data connection is active.

fn is_replay_active(&self) -> bool

Whether replay mode is active.
