Struct piston_window::glyph_cache::rusttype::GlyphCache[][src]

pub struct GlyphCache<'a, F, T> {
    pub font: Font<'a>,
    pub factory: F,
    // some fields omitted

A struct used for caching rendered font.


font: Font<'a>

The font.

factory: F

The factory used to create textures.


impl<'a, F, T> GlyphCache<'a, F, T> where
    T: CreateTexture<F> + UpdateTexture<F> + ImageSize

pub fn from_font(
    font: Font<'a>,
    factory: F,
    settings: TextureSettings
) -> GlyphCache<'a, F, T>

Constructs a GlyphCache from a Font.

pub fn new<P>(
    font: P,
    factory: F,
    settings: TextureSettings
) -> Result<GlyphCache<'static, F, T>, Error> where
    P: AsRef<Path>, 

Constructor for a GlyphCache.

pub fn from_bytes(
    font: &'a [u8],
    factory: F,
    settings: TextureSettings
) -> Result<GlyphCache<'a, F, T>, ()>

Creates a GlyphCache for a font stored in memory.

pub fn preload_chars<I>(
    &mut self,
    size: u32,
    chars: I
) -> Result<(), <T as TextureOp<F>>::Error> where
    I: Iterator<Item = char>, 

Load all characters in the chars iterator for size

pub fn preload_printable_ascii(
    &mut self,
    size: u32
) -> Result<(), <T as TextureOp<F>>::Error>

Load all the printable ASCII characters for size. Includes space.

pub fn opt_character(&self, size: u32, ch: char) -> Option<Character<'_, T>>[src]

Return ch for size if it’s already cached. Don’t load. See the preload_* functions.
