Subject: [PATCH] Fixes #179.
|
|
|
|
Boost.Python indexing suites instantiate code paths requiring stored
|
|
types to be equality comparable.
|
|
|
|
`boost::mpi::python::request_with_value` did not provide an
|
|
`operator==`, causing compilation failures.
|
|
|
|
Add the missing comparison operator and keep existing tests passing.
|
|
|
|
This is similar to other Boost.Python requirements already documented
|
|
in `py_nonblocking.hpp`.
