Trait UniverseFetch 

Source 
pub trait UniverseFetch<'a> {
    type Value;

    // Required method
    fn fetch(
        universe: &'a Universe,
        system: Entity,
    ) -> Result<Self::Value, Box<dyn Error>>;

Required Methods§

Source

fn fetch( universe: &'a Universe, system: Entity, ) -> Result<Self::Value, Box<dyn Error>>

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.
