The icon font of the backend.

const CHECKMARK_ICON: char

The char representing a ✔ icon in the ICON_FONT.

const ARROW_DOWN_ICON: char

Required Associated Types

type Font: Copy + PartialEq

The font type used.

type Paragraph: Paragraph<Font = Self::Font> + 'static

The Paragraph of this Renderer.

type Editor: Editor<Font = Self::Font> + 'static

Required Methods

fn default_font(&self) -> Self::Font

Returns the default Self::Font.

fn default_size(&self) -> Pixels

Returns the default size of Text.

fn fill_paragraph( &mut self, text: &Self::Paragraph, position: Point, color: Color, clip_bounds: Rectangle, )

Draws the given Paragraph at the given position and with the given Color.

fn fill_editor( &mut self, editor: &Self::Editor, position: Point, color: Color, clip_bounds: Rectangle, )

Draws the given Editor at the given position and with the given Color.

fn fill_text( &mut self, text: Text<String, Self::Font>, position: Point, color: Color, clip_bounds: Rectangle, )

Draws the given Text at the given position and with the given Color.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
