Struct DrawingToolRegistry

Source

pub struct DrawingToolRegistry { /* private fields */ }

Expand description

Per-manager catalogue. Register stable host-owned string ids before loading drawings. Unknown custom ids stay in storage but are not rendered or hit until registered. Clone the catalogue into a host picker to share implementations and availability.

Implementations§

Source §

impl DrawingToolRegistry

Source

pub fn register( &mut self, id: impl Into<String>, tool: RegisteredDrawingTool, ) -> Result<(), &'static str>

Registers a tool. Empty ids, zero anchors and duplicate ids leave the catalogue intact.

Source

pub fn get(&self, id: &str) -> Option<&RegisteredDrawingTool>

Looks up a custom tool by its saved id.

Source

pub fn custom_tools( &self, ) -> impl Iterator<Item = (&str, &RegisteredDrawingTool)>

Custom tool ids and metadata in stable id order for host pickers.

Source

pub fn set_availability( &mut self, tool: DrawingToolType, availability: ToolAvailability, )

Hides or disables a built-in tool. Hidden tools may still be created by the host when enabled; disabling rejects new creation through the manager and chart APIs. Duplicates, pastes and copies of its drawings are left out; restoring and syncing them is not affected.

Source

pub fn availability(&self, tool: DrawingToolType) -> ToolAvailability

Availability of a built-in tool; all tools are visible and enabled by default.

Source

pub fn builtin_tools( &self, ) -> impl Iterator<Item = (DrawingToolType, ToolAvailability)> + '_

Built-in picker entries, excluding hidden tools and including disabled entries.
