Struct DrawingState 

pub struct DrawingState {
    pub active_tool: Option<DrawingToolType>,
    pub sel_drawing: Option<usize>,
    pub magnet_mode: bool,
    pub stay_in_drawing_mode: bool,
    pub curr_color: Option<[u8; 4]>,
    pub eraser_mode: bool,
}

Snapshot of drawing-related state from the central application state.

This struct is passed to DrawingManager::sync_from_app_state at the start of each frame to ensure the manager stays in sync with toolbar selections, keyboard shortcuts, and other UI actions that modify drawing state.

Fields

active_tool: Option<DrawingToolType>

Currently selected drawing tool. None means selection/pointer mode.

sel_drawing: Option<usize>

ID of the currently selected (highlighted) drawing on the chart.

magnet_mode: bool

Whether magnet mode is enabled (snap to OHLC prices and existing drawing points).

stay_in_drawing_mode: bool

Whether to stay in drawing mode after completing a drawing (lock mode).

curr_color: Option<[u8; 4]>

Line colour every new drawing takes instead of its tool’s own, as RGBA bytes; None keeps each tool’s default.

eraser_mode: bool

Whether eraser mode is active (click to delete drawings).
