Enum Error 

#[non_exhaustive]
pub enum Error {
    AdapterNotFound,
    DeviceNotFound(RequestDeviceError),
    CreateSurface(CreateSurfaceError),
    InvalidAlphaMode(CompositeAlphaMode),
    InvalidTexture(TextureError),
    UserDefined(Box<dyn Error + Send + Sync + 'static>),
    Validation,
}

All the ways in which creating a pixel buffer can fail.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AdapterNotFound

No suitable wgpu::Adapter found

DeviceNotFound(RequestDeviceError)

Equivalent to wgpu::RequestDeviceError

CreateSurface(CreateSurfaceError)

Equivalent to wgpu::CreateSurfaceError

InvalidAlphaMode(CompositeAlphaMode)

The selected wgpu::CompositeAlphaMode is not supported by the surface

InvalidTexture(TextureError)

Equivalent to TextureError

UserDefined(Box<dyn Error + Send + Sync + 'static>)

User-defined error from custom render function

Validation

wgpu validation error

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Box<dyn Error + Sync + Send>> for Error

fn from(source: Box<dyn Error + Send + Sync + 'static>) -> Self

Converts to this type from the input type.

impl From<CreateSurfaceError> for Error

fn from(source: CreateSurfaceError) -> Self

Converts to this type from the input type.

impl From<RequestDeviceError> for Error

fn from(source: RequestDeviceError) -> Self

Converts to this type from the input type.

impl From<TextureError> for Error

fn from(source: TextureError) -> Self

Converts to this type from the input type.
