Enum FusionError 

#[non_exhaustive]
pub enum FusionError {
    SelfAliasing(FusionSelfAliasingError),
    Aliasing(FusionAliasingError),
    OverDispatch(FusionOverDispatchError),
    WorkgroupGeometry(FusionWorkgroupGeometryError),
}

Error returned when a fusion batch cannot be combined safely.

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.

SelfAliasing(FusionSelfAliasingError)

Two copies of a non-composable parser were placed in the same batch.

Aliasing(FusionAliasingError)

A cross-arm buffer alias was detected that cannot be fixed by a barrier (e.g. both arms write the same buffer without an intervening read-only phase).

OverDispatch(FusionOverDispatchError)

The fused launch geometry would over-dispatch the largest arm by more than the shared scheduling policy allows. Caller should fall back to per-arm dispatch or split the batch.

WorkgroupGeometry(FusionWorkgroupGeometryError)

An arm whose correctness depends on its own workgroup geometry was asked to run under the widened fused geometry.

Trait Implementations

impl Clone for FusionError

fn clone(&self) -> FusionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FusionError

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

Formats the value using the given formatter.

impl Eq for FusionError

impl Error for FusionError

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.
