Enum WgpuContextError 

pub enum WgpuContextError {
    NoCompatibleDevice,
    WgpuCreateSurfaceError(CreateSurfaceError),
    UnsupportedSurfaceFormat,
    RequestAdapterError(RequestAdapterError),
    RequestDeviceError(RequestDeviceError),
    PollError(PollError),
}

Errors that can occur in WgpuContext.

Variants

NoCompatibleDevice

There is no available device with the features required by Vello.

WgpuCreateSurfaceError(CreateSurfaceError)

Failed to create surface. See wgpu::CreateSurfaceError for more information.

UnsupportedSurfaceFormat

Surface doesn’t support the required texture formats. Make sure that you have a surface which provides one of TextureFormat::Rgba8Unorm or TextureFormat::Bgra8Unorm as texture formats.

RequestAdapterError(RequestAdapterError)

Wgpu failed to request an adapter

RequestDeviceError(RequestDeviceError)

Wgpu failed to request a device

PollError(PollError)

Wgpu failed to poll a device

Trait Implementations

impl Debug for WgpuContextError

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

Formats the value using the given formatter.

impl Display for WgpuContextError

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

Formats the value using the given formatter.

impl Error for WgpuContextError

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.
