Raw level conversion between *mut ffi::PyObject and PyO3 types.

Required methods

unsafe fn from_owned_ptr_or_opt(
    py: Python<'p>,
    ptr: *mut PyObject
) -> Option<&'p Self>
[src]

Convert from an arbitrary PyObject.

Safety

Implementations must ensure the object does not get freed during 'p and ensure that ptr is of the correct type. Note that it must be safe to decrement the reference count of ptr.

unsafe fn from_borrowed_ptr_or_opt(
    py: Python<'p>,
    ptr: *mut PyObject
) -> Option<&'p Self>
[src]

Convert from an arbitrary borrowed PyObject.

Safety

Implementations must ensure the object does not get freed during 'p and avoid type confusion.
