Enum RenderError 

pub enum RenderError {
    Reconfigure,
    Skip,
    Validation,
    DeviceLost,
}

A frame that produced no image, and what to do about it.

Mapped from wgpu’s CurrentSurfaceTexture; the crate root’s example handles every variant.

Variants

Reconfigure

The surface is outdated or lost: call Renderer::resize with the window’s size and draw again.

Skip

Nothing can be presented right now (the window is occluded, or the acquire timed out): try again next frame.

Validation

The surface is configured wrong for the window: call Renderer::resize with the window’s size and draw again. A surface that stays wrong is best given up with its device.

DeviceLost

The device is gone (Gpu::lost): open a new one, and a renderer on it for every window.

Trait Implementations

impl Clone for RenderError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for RenderError

impl Debug for RenderError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for RenderError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for RenderError

fn source(&self) -> Option<&(dyn Error + 'static)>

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
