Trait RenderEvent 

pub trait RenderEvent: Sized {
    // Required methods
    fn from_render_args(args: &RenderArgs, old_event: &Self) -> Option<Self>;
    fn render<U, F>(&self, f: F) -> Option<U>
       where F: FnMut(&RenderArgs) -> U;

    // Provided method
    fn render_args(&self) -> Option<RenderArgs> { ... }
}

When the next frame should be rendered.

Required Methods

fn from_render_args(args: &RenderArgs, old_event: &Self) -> Option<Self>

Creates a render event.

fn render<U, F>(&self, f: F) -> Option<U>

where F: FnMut(&RenderArgs) -> U,

Calls closure if this is a render event.

Provided Methods

fn render_args(&self) -> Option<RenderArgs>

Returns render arguments.

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.
