Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidBoundaryContract

A role-exact route schema is empty, incoherent, or not representable.

RankOutOfRange

Manifest rank is outside the declared world.

Fields

rank: usize

Invalid rank.

world_size: usize

Declared world size.

TopologyMismatch

Rank topology and complete topology disagree.

InvalidTopologyProjection

A validated core topology could not be projected consistently.

InvalidOperationLimits

Tensor/count limits were absent or incoherent for the operation.

InvalidOperationDtypes

Dtype requirements were empty or repeated.

InvalidCompletionPolicy

A bounded completion policy has no positive representable deadline.

InvalidCompletionCapabilities

Completion capability modes were absent or repeated.

DuplicateOrMissingOperation

A group requirement was empty or repeated an operation.

EmptyGroup

A group has no members.

Fields

id: CollectiveGroupId

Invalid group.

DuplicateGroupMember

A group repeats a world rank.

Fields

id: CollectiveGroupId

Invalid group.

GroupMemberOutOfRange

A group member is outside the manifest world.

Fields

id: CollectiveGroupId

Invalid group.

world_size: usize

Declared world size.

WrongLocalIndex

A group local index does not identify the manifest rank exactly.

Fields

id: CollectiveGroupId

Invalid group.

DuplicateGroupId

Group IDs are not unique.

Fields

id: CollectiveGroupId

Repeated group identity.

WrongGroupOrder

Group descriptors are not in their declared canonical order.

Fields

id: CollectiveGroupId

Invalid group.

expected: usize

Required position.

actual: usize

Declared position.

InvalidRouteEndpoints

A route is not directed between distinct endpoints.

Fields

id: CommunicationRouteId

Invalid route.

InvalidRouteOperation

A route carries a non-point-to-point operation.

Fields

id: CommunicationRouteId

Invalid route.

RouteEndpointOutOfRange

A route endpoint is outside the manifest world.

Fields

id: CommunicationRouteId

Invalid route.

world_size: usize

Declared world size.

DuplicateRouteId

Route IDs are not unique.

Fields

id: CommunicationRouteId

Repeated route identity.

WrongRouteOrder

Route descriptors are not in their declared canonical order.

Fields

id: CommunicationRouteId

Invalid route.

expected: usize

Required position.

actual: usize

Declared position.

WrongManifestCount

The number of per-rank projections does not match the world.

Fields

expected: usize

Expected world size.

actual: usize

Actual manifest count.

MissingRankManifest

No manifest was supplied for a world rank.

Fields

rank: usize

Missing world rank.

DuplicateRankManifest

More than one manifest was supplied for a world rank.

Fields

rank: usize

Repeated world rank.

IncompatibleRankManifest

A rank derived different global descriptors or local positions.

Fields

rank: usize

Incompatible world rank.

DescriptorCountOverflow

The projected descriptor count cannot be represented by the stable ID.

InvalidPeerCounts

Variable exchange counts do not match opaque group membership.

Fields

group_size: usize

Expected opaque group cardinality.

send: usize

Supplied send-count cardinality.

receive: usize

Supplied receive-count cardinality.
