Struct rusttype_bugfix_19072017::Glyph

pub struct Glyph<'a> { /* fields omitted */ }

A single glyph of a font. this may either be a thin wrapper referring to the font and the glyph id, or it may be a standalone glyph that owns the data needed by it.

A Glyph does not have an inherent scale or position associated with it. To augment a glyph with a size, give it a scale using scaled. You can then position it using positioned.

Methods

impl<'a> Glyph<'a>

fn font(&self) -> Option<&Font<'a>>

The font to which this glyph belongs. If the glyph is a standalone glyph that owns its resources, it no longer has a reference to the font which it was created from (using standalone()). In which case, None is returned.

fn get_data(&self) -> Option<Arc<SharedGlyphData>>

Get the data from this glyph (such as width, extents, vertices, etc.). Only possible if the glyph is a shared glyph.

fn id(&self) -> GlyphId

The glyph identifier for this glyph.

fn scaled(self, scale: Scale) -> ScaledGlyph<'a>

Augments this glyph with scaling information, making methods that depend on the scale of the glyph available.

fn standalone(&self) -> Glyph<'static>

Turns a Glyph<'a> into a Glyph<'static>. This produces a glyph that owns its resources, extracted from the font. This glyph can outlive the font that it comes from.

Calling standalone() on a standalone glyph shares the resources, and is equivalent to clone().

Trait Implementations

impl<'a> Clone for Glyph<'a>

fn clone(&self) -> Glyph<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
