What are all the types available in Cython?
You have basically access to most of the C types:
Here are the equivalent of all the Python types (if I do not miss some), taken from Oreilly book cython book
Python bool:
- bint (boolean coded on 4 bits, alias for short)
Python int and long
- [unsigned] char
- [unsigned] short
- [unsigned] int
- [unsigned] long
- [unsigned] long long
Python float
- float
- double
- long double
Python complex
- float complex
- double complex
Python bytes / str / unicode
- char *
- std::string
For the size_t and Py_ssite_t, keep in mind these are aliases.
Py_ssize_t is defined in python.h imported implicitly in cython. That can hold the size (in bytes) of the largest object the Python interpreter ever creates.
While size_t is a standard C89 type, defined in <stddef.h>.
