Struct FontSet 

pub struct FontSet { /* private fields */ }

The faces a frame draws with: every font loaded at init, keyed by handle, plus the face a label naming no font of its own falls back to.

Nothing compiles a font for text that names none, whichever way the world was assembled, so the renderer registers the engine’s built-in face as the fallback whenever some text needs it. A world whose text all names a Font leaves the fallback unset and pays nothing for it.

Implementations

impl FontSet

pub fn insert(&mut self, handle: FontHandle, font: LoadedFont)

Register font under handle, replacing any face already there.

pub fn set_fallback(&mut self, handle: FontHandle)

Draw labels naming no font with the face under handle.

pub fn get(&self, handle: FontHandle) -> Option<&LoadedFont>

The face registered under handle.

pub fn resolve(&self, font: Option<FontHandle>) -> Option<&LoadedFont>

The face a label draws with: the one it names, or the fallback when it names none (or names one that never loaded).

pub fn len(&self) -> usize

Number of loaded faces.

pub fn is_empty(&self) -> bool

Whether no face loaded at all, in which case no text draws.

pub fn any_atlas_slot(&self) -> Option<usize>

Atlas slot of an arbitrary loaded face, which the sprite shaper uses as the texture slot for its untextured (sentinel-UV) quads.

impl Default for FontSet

fn default() -> FontSet
