Struct piet::FontFamily

pub struct FontFamily(_);

A reference to a font family.

This may be either a CSS-style “generic family name”, such as “serif” or “monospace”, or it can be an explicit family name.

To use a generic family name, use the provided associated constants: FontFamily::SERIF, FontFamily::SANS_SERIF, FontFamily::SYSTEM_UI, and FontFamily::MONOSPACE.

To use a specific font family you should not construct this type directly; instead you should verify that the desired family exists, via the Text::font API.

Implementations

impl FontFamily

pub const SANS_SERIF: FontFamily

A san-serif font, such as Arial or Helvetica.

pub const SERIF: FontFamily

A serif font, such as Times New Roman or Charter.

pub const SYSTEM_UI: FontFamily

The platform’s preferred UI font; San Francisco on macOS, and Segoe UI on recent Windows.

pub const MONOSPACE: FontFamily

A monospace font.

pub fn new_unchecked(s: impl Into<Arc<str>>) -> Self

Create a new font family with a given name, without verifying that it exists.

This should generally not be used; instead you should create a FontFamily by calling the Text::font_family method, which verifies that the family name exists.

pub fn name(&self) -> &str

The name of the font family.

pub fn is_generic(&self) -> bool

Returns true if this is a generic font family.
