pub trait Has<T> {
// Required method
fn retrieve(&self) -> &T;
}Expand description
Used to represent types that can provide a certain context type.
If you don’t know what this is, you most likely want to pass ctx.
This trait is basically syntactical sugar, saving you from having to split contexts when you don’t need to and also shortening calls like
canvas.finish(&mut ctx.gfx)?;into just
canvas.finish(ctx)?;
