Enum ComputeError 

pub enum ComputeError {
    NoAdapter,
    DeviceRequest(String),
    OutOfMemory,
    ShaderCompilation(String),
    Operation {
        op: &'static str,
        detail: String,
    },
}

Errors that can occur while initialising or using a GPU compute context.

Variants

NoAdapter

No GPU adapter was found on this host (headless CI, VM without GPU, …).

Callers should treat this as a graceful skip, not a hard failure.

DeviceRequest(String)

The adapter was found but the device/queue request failed.

The contained string carries the underlying wgpu diagnostic.

OutOfMemory

A GPU memory allocation failed or the device reported an out-of-memory condition via an error scope.

ShaderCompilation(String)

WGSL shader compilation failed.

The contained string carries the diagnostic message including line and column numbers as reported by wgpu::CompilationInfo.

Operation

A compute operation failed with structured context.

op names the failing operation (e.g. "read_back", "dispatch"); detail carries the parameters or wgpu-level message.

Fields

op: &'static str

The name of the failing operation.

detail: String

Human-readable detail: parameters, buffer labels, entry-point names, etc.

Trait Implementations

impl Debug for ComputeError

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

Formats the value using the given formatter.

impl Display for ComputeError

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

Formats the value using the given formatter.

impl Error for ComputeError

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.
