Struct CommunicationGroupDescriptor 

pub struct CommunicationGroupDescriptor { /* private fields */ }

Ordered membership and exact requirements for one opaque group.

Implementations

impl CommunicationGroupDescriptor

pub fn new( id: CollectiveGroupId, creation_order: usize, members: Vec<usize>, local_index: Option<usize>, requirements: CommunicationGroupRequirements, ) -> Result<Self, CommunicationManifestError>

Validates local ordered membership independent of world geometry.

pub const fn id(&self) -> CollectiveGroupId

Opaque stable group identity.

pub const fn creation_order(&self) -> usize

Canonical group-creation position shared by every world rank.

pub fn members(&self) -> &[usize]

Ordered world-rank membership.

pub const fn local_index(&self) -> Option<usize>

This manifest rank’s position, or None when it does not participate.

pub const fn requirements(&self) -> &CommunicationGroupRequirements

Exact operations and limits required on the group.

pub fn collective_descriptor(&self) -> Option<CollectiveGroupDescriptor>

Returns the established core descriptor when this rank participates.

Backends can consume this narrow local descriptor without learning the semantic topology that produced it.
