Struct conrod_glium::GlyphCache

pub struct GlyphCache { /* fields omitted */ }

A rusttype GlyphCache along with a glium::texture::Texture2d for caching text on the GPU.

Methods

impl GlyphCache

pub fn with_dimensions<F>(
    facade: &F,
    width: u32,
    height: u32
) -> Result<Self, TextureCreationError> where
    F: Facade, 

Construct a GlyphCache with the given texture dimensions.

When calling GlyphCache::new, the get_framebuffer_dimensions method is used to produce the width and height. However, often creating a texture the size of the screen might not be large enough to cache the necessary text for an application. The following constant multiplier is used to ensure plenty of room in the cache.

pub fn new<F>(facade: &F) -> Result<Self, TextureCreationError> where
    F: Facade, 

Construct a GlyphCache with a size equal to the given Display's current framebuffer dimensions.

pub fn texture(&self) -> &Texture2d

The texture used to cache the glyphs on the GPU.
