Trait PhaseItem

Source 
pub trait PhaseItem {

    // Required methods
    fn sort_key(&self) -> Self::SortKey;
    fn draw_function(&self) -> &dyn Draw<Self>;
}

fn draw_function(&self) -> &dyn Draw<Self>

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
