Trait App 

pub trait App {
    type Renderer: Frenderer;

    const DT: f32;

    // Required methods
    fn new(renderer: &mut Self::Renderer, assets: AssetCache) -> Self;
    fn update(&mut self, renderer: &mut Self::Renderer, input: &Input);
    fn render(&mut self, renderer: &mut Self::Renderer, dt: f32, input: &Input);
}

App is the main public trait of frapp. Implementors get a defined new/update/render lifecycle with a choice of frenderer renderers (either frenderer::Renderer or frenderer::Immediate).

Required Associated Constants

const DT: f32

Target delta-time for simulation

Required Associated Types

type Renderer: Frenderer

The renderer type to use

Required Methods

fn new(renderer: &mut Self::Renderer, assets: AssetCache) -> Self

Initialize the app

fn update(&mut self, renderer: &mut Self::Renderer, input: &Input)

Update (called every DT seconds)

fn render(&mut self, renderer: &mut Self::Renderer, dt: f32, input: &Input)

Render (called once per present cycle)

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.
