Enum RenderError 

pub enum RenderError {
    NoAdapter(String),
    Device(String),
    InvalidSize {
        width: u32,
        height: u32,
        max: u32,
    },
    Readback(String),
}

A failure to render offscreen.

Variants

NoAdapter(String)

No wgpu adapter is available, for example on a machine without a GPU or a software rasteriser.

Device(String)

The adapter refused to create a device.

InvalidSize

The requested image is empty or exceeds the adapter’s maximum texture dimension.

Fields

width: u32

height: u32

max: u32

Readback(String)

The rendered image could not be read back from the GPU.

Trait Implementations

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for RenderError

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

Returns the lower-level source of this error, if any.

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.

impl From<RenderError> for ExportError

fn from(source: RenderError) -> Self

Converts to this type from the input type.
