Struct ResolvedGlyph

Source

pub struct ResolvedGlyph { /* private fields */ }

Expand description

A glyph resolved from a FontChain: the glyph index plus the specific BitmapFont it came from, since each font in a chain owns its own bitmap data.

Implementations§

Source §

impl ResolvedGlyph

Source

pub const fn font(&self) -> BitmapFont

The font this glyph was resolved from.

Source

pub const fn font_index(&self) -> usize

The position of font within the chain that resolved it: 0 is the primary font, 1.. the fallbacks in order.

A GPU backend packs every font in the chain into one atlas and addresses a glyph by a flat slot, so it needs the font’s position (a stable index into FontChain::fonts) rather than the font value, which carries no identity of its own.

Source

pub const fn index(&self) -> u8

The glyph index within font, always < font().glyph_count().

Source

pub const fn is_notdef(&self) -> bool

Whether this is the substituted “no glyph” box rather than a glyph for the character that was asked for: true when no font in the chain covered that character and FontChain::resolve fell back to the solid block.

Source

pub fn rows(&self) -> &[u8] ⓘ

Returns the row bytes for this glyph; see BitmapFont::rows.

where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
