This is a useful API in long-running Rust code, which lets users
cancel evaluation by pressing Ctrl-C, and run any other signal
handlers that have been set using the signal module.
* Fix compilation on platforms that don't use i8 for c_char
This commit changes the cast of an c_char to be a c_char type instead of
i8. On x86 platforms i8 == c_char, but it can also be u8 on other
platforms. [1][2] This should fix compilation on those platforms by just
using the c_char type so that we're casting as the right type regardless
of which platform PyO3 is being built for.
Fixes#1181

* Add changelog entry
* Added a couple basic tests
* Implemented suggested change
* Fixed type inference
* cargo fmt
* Finished tests and removed warnings
* Include in CHANGELOG.md
* Moved test into separate file
* &'static str and function rename
* Mention in the book
* Add (failing) tests for issue #1064
* Return NotImplemented when richcmp doesn't match the expected type.
* Fix tests that expect TypeError when richcmp returns NotImplemented.
- The python code 'class Other: pass; c2 {} Other()' was raising a NameError:
c2 not found
- eq and ne never raise a TypeError, so I split the those cases.
* Return NotImplemented for number-like binary operations.
* Add dummy impl PyNumberProtocol for the test struct.
* Rework tests of NotImplemented.
* Make py_ternary_num_func return NotImplemented when type mismatches.
* Return NotImplement for type mismatches in binary inplace operators.
* Reduce boilerplate with `extract_or_return_not_implemented!`
* Extract common definition 'Other' into a function.
* Test explicitly for NotImplemented in the __ipow__ test.
* Add entry in CHANGELOG for PR #1072.
* Add the section 'Emulating numeric types' to the guide.
* Ensure we're returning NotImplemented in tests.
* Simplify the tests: only test we return NotImplemented.
Our previous test were rather indirect: were relying that Python
behaves correctly when we return NotImplemented.
Now we only test that calling a pyclass dunder method returns NotImplemented
when the argument doesn't match the type signature. This is the expected
behavior.
* Remove reverse operators in tests of NotImplemented
The won't be used because of #844.
* Apply suggestions from code review
