Enum GpuInitError 

#[non_exhaustive]
pub enum GpuInitError {
    CreateSurface(CreateSurfaceError),
    RequestAdapter,
    RequestDevice,
    CopySrcUnsupported,
    NoSurfaceFormats,
    NoAlphaModes,
}

Why Gpu::new could not produce a usable surface.

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.

CreateSurface(CreateSurfaceError)

RequestAdapter

RequestDevice

CopySrcUnsupported

CopySrc::Required was asked for and the surface does not offer it.

NoSurfaceFormats

The surface reported no supported texture formats — a torn-down or otherwise unusable surface.

NoAlphaModes

The surface reported no supported composite alpha modes.

Trait Implementations

impl Debug for GpuInitError

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

Formats the value using the given formatter.

impl Display for GpuInitError

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

Formats the value using the given formatter.

impl Error for GpuInitError

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.
