}

A graphics backend that supports text rendering.

Required Associated Constants

const ICON_FONT: Font

The icon font of the backend.

const CHECKMARK_ICON: char

The char representing a ✔ icon in the ICON_FONT.

const ARROW_DOWN_ICON: char

The char representing a ▼ icon in the built-in ICON_FONT.

Required Methods

fn default_size(&self) -> u16

Returns the default size of text.

fn measure(&self, contents: &str, size: f32, font: Font, bounds: Size) -> (f32, f32)

Measures the text contents with the given size and font, returning the size of a laid out paragraph that fits in the provided bounds.

fn hit_test(
    &self,
    contents: &str,
    size: f32,
    font: Font,
    bounds: Size,
    point: Point,
    nearest_only: bool
) -> Option<Hit>

Tests whether the provided point is within the boundaries of Text laid out with the given parameters, returning information about the nearest character.

If nearest_only is true, the hit test does not consider whether the the point is interior to any glyph bounds, returning only the character with the nearest centeroid.
