Enum WgpuInitError 

pub enum WgpuInitError {
    NoAdapter,
    NotAvailable,
    DeviceRequestFailed(String),
    FeatureDisabled,
    DeviceRequest(String),
    InvalidHandle(usize),
    PoisonedLock,
}

Error returned when the wgpu backend cannot be initialised.

Variants

NoAdapter

No compatible GPU adapter was found.

NotAvailable

The wgpu-backend feature is not enabled; this is a stub build.

DeviceRequestFailed(String)

The device request failed (e.g. out of memory).

FeatureDisabled

A required GPU feature is disabled or not supported.

DeviceRequest(String)

Device creation failed with the given error string.

InvalidHandle(usize)

A buffer handle is out of range.

PoisonedLock

A mutex was poisoned (should not occur in practice).

Trait Implementations

impl Clone for WgpuInitError

fn clone(&self) -> WgpuInitError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WgpuInitError

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

Formats the value using the given formatter.

impl Display for WgpuInitError

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

Formats the value using the given formatter.

impl Error for WgpuInitError

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 PartialEq for WgpuInitError

fn eq(&self, other: &WgpuInitError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
