        graphics: &mut Graphics,
        size: Option<f32>,

Trait that all loadable assets must implement

Required Methods

fn load( path: PathBuf, graphics: &mut Graphics, size: Option<f32>, ) -> Result<Box<dyn LoadableResource>>

where Self: Sized,

Load a resource from path and return it boxed

Arguments

path: path to the resoruce file graphics: current Graphics instance which holds texture_creator and ttf_context size: optional size for any resoruce that needs it

Errors

Returns an error if the file cannot be read or parsed

fn name(&self) -> String

Eaasy-to-use identifier for the resource

Provided Methods

fn as_mut_slice(&self) -> Option<&mut [u8]>

Return a mutable slice that the graphics thread can pass to SDL

If the resource does not have a buffer, then it mustn’t implement this function

fn as_slice(&self) -> Option<Ref<'_, [u8]>>

Return an immutable slice for read‑only access

If the resource does not have a buffer, then it mustn’t implement this function
