Struct TextureCache

pub struct TextureCache { /* private fields */ }

This is the structure for the TextureCache.

Implementations

impl TextureCache

This is a Texture cache object that is used by the WidgetCache. This is responsible for loading in images into a cache in memory so that it can be copied multiple times as required by the application.

pub fn new() -> Self

Creates a new TextureCache.

pub fn get_ttf_context(&self) -> &Sdl2TtfContext

Retrieves the current Text Rendering context (Sdl2TtfContext)

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

Loads an image based on the image_name, which is the filename for the image to load. Returns a reference to the Texture that was loaded.

pub fn render_text( &mut self, c: &mut Canvas<Window>, font_name: String, font_size: u16, font_style: FontStyle, font_string: String, font_color: Color, width: u32, ) -> (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

Returns the “default value” for a type.
