Struct ReferenceTopology 

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

Combinatorial topology of one runtime-dimensional reference cell.

Simplex entities are non-empty subsets of d + 1 vertices. Hypercube entities are generated from fixed-lower, fixed-upper, or free state on every axis. These native combinatorial definitions avoid dimension-specific tables while retaining deterministic entity ordering.

Implementations§

§

impl ReferenceTopology

Signature links:§ReferenceTopology

pub fn new(cell: ReferenceCell) -> Result<ReferenceTopology, Diagnostic>

Signature links:newReferenceCellResultReferenceTopologyDiagnostic

Generate a checked topology for a reference cell.

§Errors

Returns EQ0803 when combinatorial counts overflow or exceed the inspectable artifact resource limits.

pub const fn reference_cell(&self) -> ReferenceCell

Signature links:reference_cellReferenceCell

Reference cell described by this topology.

pub fn entity_count(&self, dimension: usize) -> Option<usize>

Signature links:entity_countusizeOptionusize

Number of entities in a dimension stratum.

pub fn entity(&self, dimension: usize, index: usize) -> Option<&ReferenceEntity>

Signature links:entityusizeusizeOptionReferenceEntity

Retrieve an entity by dimension and stratum-local index.

pub fn incidence( &self, entity_dimension: usize, entity_index: usize, target_dimension: usize, ) -> Option<Vec<ReferenceIncidence>>

Signature links:incidenceusizeusizeusizeOptionVecReferenceIncidence

Incidence in either direction, in deterministic stratum order.

The same local_ordinal is returned when querying a containing entity’s closure or the reverse adjacency. Invalid entities or dimensions return None; valid non-incident strata return an empty vector.
