Struct ErasedFusedPlan 

pub struct ErasedFusedPlan { /* private fields */ }

Dtype-erased single-output wrapper around FusedPlan.

This is the erased replay boundary for unary map and zip-map elementwise families. It supports the same runtime op-code vocabulary as FusedPlan, but only for the scalar dtypes currently implementing FusedScalar.

Implementations

impl ErasedFusedPlan

pub fn compile(dtype: KernelDType, plan: FusedPlan) -> Result<Self>

Validate and store a single-output fused elementwise plan for one dtype.

pub fn dtype(&self) -> KernelDType

pub fn plan(&self) -> &FusedPlan

pub fn execute( &self, ctx: &ExecContext, dest: &mut ErasedRawStridedMut<'_>, inputs: &[ErasedRawStridedRef<'_>], ) -> Result<()>

Execute a single-output fused elementwise plan through erased descriptors.

pub fn execute_uninit( &self, ctx: &ExecContext, dest: &mut ErasedRawStridedUninitMut<'_>, inputs: &[ErasedRawStridedPtr<'_>], ) -> Result<()>

Execute a single-output fused plan into fully overwritten uninitialized storage.

Dtype, shape, destination injectivity, bounds, and input/output overlap are validated before any shared typed input descriptor is formed or any destination byte is written. On Ok(()), every logical destination element is initialized. An error leaves the destination untouched; a panic during execution may leave partial initialization, but the backing MaybeUninit storage remains safe to drop.

Errors

Returns a typed dtype, input-count, shape, bounds, destination injectivity, unsupported-operation, or input/output-overlap error. All error-producing validation completes before execution starts. On success, every reachable destination slot is fully overwritten; unreachable holes are neither read nor initialized. Validation errors are returned before any destination write. A panic during execution may leave a partially initialized MaybeUninit destination, which is still safely droppable; no readable value is promised for unwritten reachable slots.
