Trait mterm::App

pub trait App {
    fn tick(&mut self, tick_input: TickInput) -> TickResult;
    fn present(&self, present_input: PresentInput<'_>) -> PresentResult;
}

Application trait for hooking into the main loop of mterm.

mterm manages Winit and wgpu for you to provide an interface between it and your application. The application author is required to implement 2 methods from the trait: tick and present.

tick is called everytime an event is triggered in the main loop. It receivs a TickInput structure that contains various information such as any key presses, mouse movements and clicks, and some stats. Using this information the application can execute its logic. This method should also return a TickResult value to tell the main loop whether to continue or stop and exit the application.

present is called whenever the application is required to render itself. mterm provides the method with a few u32 arrays via a PresentInput structure. These arrays can be mutated to change what appears in the window. This method should return a PresentResult to tell the main loop if anything changed and needs to be rendered.

Required methods

fn tick(&mut self, tick_input: TickInput) -> TickResult

fn present(&self, present_input: PresentInput<'_>) -> PresentResult
