mpi-0.6.0

2022-08-05

MSRV: 1.54.0

Notes

In order to use the user-operations optional feature (enabled by default), you may want to check
that you are using at least libffi-sys version 1.1.0. This can be done by running cargo update, but for most users this will likely be unnecessary.

• [PR 110] Implement Buffer and BufferMut for Vec,
  allowing cleaner syntax

• [PR 52] Safely send and receive structs with arbitrary
