• filenames - The name of the file(s) to load. This can be a single string or a vector of strings.
• handler - A callback function that is invoked when the file is loaded.

pub fn update_item(filename: &str, content: &str)

Arguments

• filename - The name of the file to update.
• content - The new content for the file.

pub fn update_texture(filename: &str, texture: &Texture2D)

Updates the texture object of the specific filename loaded in the cache. If the texture object of filename does not exist in the cache, it will be added into the cache.

Arguments

• filename - The name of the texture to update.
• texture - The new texture object for the file.

pub fn unload_item_or_type(name: &str) -> bool

• bool - true if the resource was unloaded successfully, false otherwise.

pub fn unload()

pub fn remove_unused()

Removes all unused resources (not being referenced) from the cache.

pub fn remove_unused_by_type(type_name: &str)

Removes all unused resources of the given type from the cache.

Arguments

• resource_type - The type of resource to remove. This could be one of “Texture”, “SVG”, “Clip”, “Frame”, “Model”, “Particle”, “Shader”, “Font”, “Sound”, “Spine”.
