AssemblyAccumulator

eqiora::assembly

Struct AssemblyAccumulator 

pub struct AssemblyAccumulator<S> { /* private fields */ }
Description

Shared ordered scatter state for assembly backend implementors.

Backends may evaluate packets under any placement, but must present them here exactly once in increasing logical index order. This type owns the numerical accumulation tree used by both reference and parallel paths.

Implementations§

§

impl<S> AssemblyAccumulator<S>
where S: Scalar + ComplexFloat + Sync,

Signature links:§AssemblyAccumulatorScalarComplexFloatSync

pub fn new(plan: &AssemblyPlan) -> Result<AssemblyAccumulator<S>, Diagnostic>

Signature links:newAssemblyPlanResultAssemblyAccumulatorDiagnostic

Allocate one deterministic accumulator per planned target.

§Errors

Propagates invalid target shape as EQ0806.

pub const fn plan(&self) -> &AssemblyPlan

Signature links:planAssemblyPlan

Plan used to validate packet-local projections before ordered scatter.

pub fn scatter_packet( self, packet_index: usize, packet: &AssemblyPacket<S>, ) -> Result<AssemblyAccumulator<S>, Diagnostic>

Signature links:scatter_packetusizeAssemblyPacketResultAssemblyAccumulatorDiagnostic

Scatter the next logical packet through the common ordered path.

§Errors

Returns EQ0806 for skipped/repeated indices, a target outside the plan, invalid global DOFs, or non-finite accumulation.

pub fn scatter_projected( self, packet_index: usize, projected: &[TargetAssemblyDelta<S>], ) -> Result<AssemblyAccumulator<S>, Diagnostic>

Signature links:scatter_projectedusizeTargetAssemblyDeltaResultAssemblyAccumulatorDiagnostic

Accumulate one plan-validated projection in logical packet order.

This is the single stateful scatter path shared by serial packet assembly and backends that project packets independently.

Prepared projections must retain this exact plan’s complete structural identity, logical packet index and target inventory. Unprepared plans retain target/dimension admission and ordered packet provenance.

§Errors

Returns EQ0806 for skipped/repeated indices, empty or foreign-plan projections, invalid global DOFs, or non-finite accumulation.

pub fn finish( self, execution: ExecutionReport, ) -> Result<AssemblyResult<S>, Diagnostic>

Signature links:finishExecutionReportResultAssemblyResultDiagnostic

Finalize all targets and attach exact execution evidence.

§Errors

Returns EQ0806 if any target has an empty structural row.
