Struct Eraser 

pub struct Eraser { /* private fields */ }

An eraser is a tool intended for erasing.

This is represented in the physical design of the tool. Typically an eraser is on the back end of a Stylus to emulate a traditional pencil + eraser setup.

Erasers never exist on their own, they are part of a Tool::StylusWithEraser and always coupled with a corresponding Stylus.

Trait Implementations

impl Clone for Eraser

fn clone(&self) -> Eraser

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Eraser

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Eraser

fn eq(&self, other: &Eraser) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToolFeatures for Eraser

fn name(&self) -> &str

The name of this eraser given by the manufacturer, e.g. “Grip Pen”. This name is suitable for presentation.

This name may not be unique. Using this name is not usually required, the eraser does not live without its corresponding stylus and the stylus name is a better option for presentation.

fn vendor_id(&self) -> VendorId

The vendor ID of the eraser. Theoretically this may be different to the Stylus::vendor_id() but no such devices have been observed in the wild yet.

fn tool_id(&self) -> ToolId

The tool ID of the eraser.

fn buttons(&self) -> &[ToolButton]

The buttons on this Eraser, if any

fn axes(&self) -> &[Axis]
