Struct graphics::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.
Fields
font: Font<'a>The font.
factory: FThe factory used to create textures.

factory: F,
settings: TextureSettings
) -> Result<GlyphCache<'a, F, T>, ()>[src]
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: FontSize,
chars: I
) -> Result<(), T::Error> where
I: Iterator<Item = char>, [src]
&mut self,
size: FontSize,
chars: I
) -> Result<(), T::Error> where
I: Iterator<Item = char>,
Load all characters in the chars iterator for size
pub fn preload_printable_ascii(
&mut self,
size: FontSize
) -> Result<(), T::Error>[src]
&mut self,
size: FontSize
) -> Result<(), T::Error>
Load all the printable ASCII characters for size. Includes space.
pub fn opt_character(
&self,
size: FontSize,
ch: char
) -> Option<Character<'_, T>>[src]
&self,
size: FontSize,
ch: char
) -> Option<Character<'_, T>>
Return ch for size if it’s already cached. Don’t load.
See the preload_* functions.
