WebIn the example above, the type of the local variable a in myfunction () is not fixed and will thus be a Python object. To statically type it, one can use Cython’s @cython.locals decorator (see Magic Attributes , and Magic Attributes within the .pxd ). Normal Python ( def) functions cannot be declared in .pxd files. WebThe most common way to wrap a C++ class is to use Extension types. As an extension type a just a C struct, it can have an underlying C++ class as a field and act as a proxy to it. However, there are some complications. C structs are created as plain memory chunks, but C++ classes are always created with a constructor.
