Struct pushrod_widgets::caches::TextureCache

pub struct TextureCache { /* fields omitted */ }

This is a storage object for the TextureCache.

Implementations

impl TextureCache

The TextureCache provides a mechanism for caching images, and returning the current text rendering context.

pub fn get_ttf_context(&self) -> &Sdl2TtfContext

Returns the currently available text context as a reference.

pub fn get_image(
    &mut self,
    c: &mut Canvas<Window>,
    image_name: String
) -> &Texture

Returns an image loaded into a Texture reference, caching it in memory.

pub fn render_text(
    &mut self,
    c: &mut Canvas<Window>,
    properties: &mut WidgetProperties,
    alt_color: Option<Color>
) -> (Texture, u32, u32)

Renders text, given the font name, size, style, color, string, and max width. Transfers ownership of the Texture to the calling function, returns the width and height of the texture after rendering. By using the identical font name, size, and style, if SDL2 caches the font data, this will allow the font to be cached internally.

Trait Implementations

impl Default for TextureCache

fn default() -> Self
