Module nccl_common 

Types shared between the real NCCL bindings (nccl) and the CPU-only stubs (nccl_stubs).

These types have no dependency on the nccl-sys FFI and are always compiled. Keeping them here removes duplication and guarantees both code paths see an identical public API.

Structs

NcclGroupTicket

A ticket that we use to link group start/end calls. Does not implement Send, to enforce that group start and end calls are on the same thread.

Enums

DataType

Rust version of ncclDataType_t.

NcclError

Types of errors that the safe Communicator API can return.

NcclStatus

RawNcclError

Corresponds to ncclResult_t error cases.
