Struct DistributedCsr 

pub struct DistributedCsr { /* private fields */ }
Description

One square CSR operator lowered into owned-row shards and a halo plan.

Implementations§

§

impl DistributedCsr

Signature links:§DistributedCsr

pub fn from_global_csr( partition: Partition, row_offsets: &[usize], column_indices: &[usize], values: &[f64], ) -> Result<DistributedCsr, Diagnostic>

Signature links:from_global_csrPartitionusizeusizef64ResultDistributedCsrDiagnostic

Partition a finite square global CSR artifact.

This is an explicit realization copy: each shard retains only its owned rows, with global column indices used to derive ghost storage.

§Errors

Returns EQ0807 for malformed CSR structure, non-finite values, or a non-f64 global space.

pub const fn partition(&self) -> &Partition

Signature links:partitionPartition

Unique global ownership map.

pub fn layouts(&self) -> &[LocalLayout]

Signature links:layoutsLocalLayout

Local layouts in partition-index order.

pub const fn halo(&self) -> &HaloPlan

Signature links:haloHaloPlan

Derived deterministic halo plan.

pub fn shard(&self, partition: PartitionId) -> Option<LocalCsrShard<'_>>

Signature links:shardPartitionIdOptionLocalCsrShard

Owned-row shard for one partition.
