Struct LocalToGlobalMap 

pub struct LocalToGlobalMap { /* private fields */ }

Mapping from local point/DOF pairs to unique global indices.

Implementations

impl LocalToGlobalMap

pub fn from_section_with_tags_and_ownership<V, S, C>( section: &Section<V, S>, overlap: &Overlap, ownership: &PointOwnership, comm: &C, my_rank: usize, tags: SectionCommTags, ) -> Result<Self, MeshSieveError>

where S: Storage<V>, C: Communicator + Sync,

Build a global numbering map using explicit communication tags and ownership data.

pub fn from_section_with_ownership<V, S, C>( section: &Section<V, S>, overlap: &Overlap, ownership: &PointOwnership, comm: &C, my_rank: usize, ) -> Result<Self, MeshSieveError>

where S: Storage<V>, C: Communicator + Sync,

Build a global numbering map using ownership metadata and a legacy default tag (0xBEEF).

pub fn from_section_with_constraints_and_ownership<V, S, C, CS>( section: &Section<V, S>, constraints: &CS, overlap: &Overlap, ownership: &PointOwnership, comm: &C, my_rank: usize, tags: SectionCommTags, ) -> Result<Self, MeshSieveError>

where S: Storage<V>, C: Communicator + Sync, CS: ConstraintSet<V>,

Build a global numbering map using a section, constraints, and ownership data.

pub fn from_multi_section_with_tags_and_ownership<V, S, C>( section: &MultiSection<V, S>, overlap: &Overlap, ownership: &PointOwnership, comm: &C, my_rank: usize, tags: SectionCommTags, ) -> Result<Self, MeshSieveError>

where S: Storage<V>, C: Communicator + Sync,

Build a global numbering map using a multi-section and ownership data.

pub fn from_multi_section_with_ownership<V, S, C>( section: &MultiSection<V, S>, overlap: &Overlap, ownership: &PointOwnership, comm: &C, my_rank: usize, ) -> Result<Self, MeshSieveError>

where S: Storage<V>, C: Communicator + Sync,

Build a global numbering map for a multi-section using a legacy default tag (0xBEEF).

pub fn global_offset(&self, point: PointId) -> Result<u64, MeshSieveError>

Return the global offset (start index) for a point.

pub fn global_index( &self, point: PointId, dof: usize, ) -> Result<u64, MeshSieveError>

Return the global index for a local point/DOF pair.

pub fn global_range(&self, point: PointId) -> Result<Range<u64>, MeshSieveError>

Return the global DOF range [start, end) for a point.

pub fn remap_points<I>(&self, new_to_old: I) -> Result<Self, MeshSieveError>

where I: IntoIterator<Item = (PointId, PointId)>,

Return a copy of this numbering with point IDs remapped.

new_to_old maps each point in the returned map to the corresponding point in this map. Offsets and DOF lengths are preserved, which is useful for compact submeshes that must keep parent global numbering semantics.

pub fn total_dofs(&self) -> u64

Total number of globally owned DOFs across all ranks.
