[−][src]Struct graphics::glyph_cache::rusttype::GlyphCache

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

A struct used for caching rendered font.

Fields

font: Font<'a>

The font.

factory: F

The factory used to create textures.

Implementations

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

pub fn from_font(font: Font<'a>, factory: F, settings: TextureSettings) -> Self[src]

Constructs a GlyphCache from a Font.

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

Constructor for a GlyphCache.

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

Creates a GlyphCache for a font stored in memory.

pub fn preload_chars<I>(
    &mut self,
    size: FontSize,
    chars: I
) -> Result<(), T::Error> where
    I: Iterator<Item = char>, [src]

Load all characters in the chars iterator for size

pub fn preload_printable_ascii(
    &mut self,
    size: FontSize
) -> Result<(), T::Error>[src]

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

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

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

Trait Implementations

impl<'b, F, T: ImageSize> CharacterCache for GlyphCache<'b, F, T> where
    T: CreateTexture<F> + UpdateTexture<F>, [src]

type Texture = T

The texture type associated with the character cache.

type Error = T::Error

The error type associated with the character cache.
