Trait RenderBackend 

pub trait RenderBackend {
    // Required methods
    fn configure_surface(&mut self, width: u32, height: u32) -> (u32, u32);
    fn frame(&mut self, scene: &Scene, glyph_cfg: GlyphRasterConfig) -> bool;
}

Required Methods

fn configure_surface(&mut self, width: u32, height: u32) -> (u32, u32)

Configure the framebuffer for width x height and return the size actually used.

Device texture limits can make the framebuffer smaller than the viewport, so the caller must adopt the returned size for layout and hit testing. Anything else lets the scene project against one size while input is resolved against another.

fn frame(&mut self, scene: &Scene, glyph_cfg: GlyphRasterConfig) -> bool

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
