MpiSpatialAssemblyBackend

eqiora::backends::mpi

Struct MpiSpatialAssemblyBackend 

pub struct MpiSpatialAssemblyBackend<'group> { /* private fields */ }
Description

MPI transport adapter for the transport-neutral distributed assembly protocol.

The backend borrows one application-owned execution group exclusively for its complete lifetime. Each assemble call is one serialized collective stream; ownership, route admission, canonical folding, shard validation, and reconstruction remain owned by eqiora-spatial-distribution.

Implementations§

§

impl<'group> MpiSpatialAssemblyBackend<'group>

Signature links:§MpiSpatialAssemblyBackend

pub fn new( group: &'group mut MpiExecutionGroup, layout: DistributedMeshLayout, ) -> Result<MpiSpatialAssemblyBackend<'group>, Diagnostic>

Signature links:newMpiExecutionGroupResultMpiSpatialAssemblyBackendDiagnostic

Collectively bind an exact distributed mesh layout to an MPI group.

Every rank must call this constructor in the same collective order. A layout mismatch, including a foreign mesh revision on one rank, is rejected on every rank before an assembly operation can begin.

§Errors

Returns EQ0806 on every rank for a communicator/layout shape or identity disagreement.

pub const fn layout(&self) -> &DistributedMeshLayout

Signature links:layout

Exact mesh layout collectively bound at construction.

pub fn accepted_evidence( &self, ) -> Result<Option<DistributedAssemblyEvidence>, Diagnostic>

Signature links:accepted_evidenceResultOptionDiagnostic

Evidence from the latest successful collective call, if any.

A failed call clears prior evidence. An active operation is rejected instead of exposing a partial receipt.

§Errors

Returns EQ0806 if the operation/evidence cell is already borrowed.
