Required methods

pub fn contains(&self, uri: &str) -> bool[src]

contains: @self: A #TextureCache @uri: A URI or path to an image file

Checks whether the given URI/path is contained within the texture cache.

Returns: %true if the image exists, %false otherwise

pub fn get_cogl_texture(&self, uri: &str) -> Option<Handle>[src]

contains_meta: @self: A #TextureCache @uri: A URI or path to an image file @ident: A unique identifier

Checks whether there are any textures associated with the given URI by the given identifier.

Returns: %true if the data exists, %false otherwise

get_cogl_texture: @self: A #TextureCache @uri: A URI or path to an image file

Create a #CoglHandle representing a texture of the specified image. Adds the image to the cache if the image had not been previously loaded. Subsequent calls with the same image URI/path will return the #CoglHandle of the previously loaded image with an increased reference count.

Returns: (transfer none): a #CoglHandle to the cached texture

pub fn get_size(&self) -> usize[src]

get_meta_cogl_texture: @self: A #TextureCache @uri: A URI or path to an image file @ident: A unique identifier

Retrieves the #CoglHandle of the previously added image associated with the given unique identifier.

See insert_meta()

Returns: (transfer full): A #CoglHandle to a texture, with an added reference. %None if no image was found.

get_size: @self: A #TextureCache

Returns the number of items in the texture cache

Returns: the current size of the cache

pub fn insert(&self, uri: &str, texture: Handle)[src]

insert: @self: A #TextureCache @uri: A URI or local file path @texture: A #CoglHandle to a texture

Inserts a texture into the texture cache. This can be useful if you want to cache a texture from a custom or unhandled URI type, or you want to override a particular texture.

If the image is already in the cache, this texture will replace it. A reference will be taken on the given texture.

pub fn load_cache(&self, filename: &str)[src]

insert_meta: @self: A #TextureCache @uri: A URI or local file path @ident: A unique identifier @texture: A #CoglHandle to a texture @destroy_func: An optional destruction function for @ident

Inserts a texture that’s associated with a URI into the cache. If the metadata already exists for this URI, it will be replaced.

This is useful if you have a widely used modification of an image, for example, an image with a border composited around it.
