Detailed Description

RAII wrapper that commits an MPI_Datatype on construction and frees it on destruction.

Calls MPI_Type_commit / MPI_Type_free directly and does not depend on the KaMPIng environment. Useful for managing custom derived datatypes with automatic lifetime.

The documentation for this class was generated from the following file:
