Struct PySlice

Source 
pub struct PySlice(/* private fields */);
Expand description

Represents a Python slice.

Values of this type are accessed via PyO3’s smart pointers, e.g. as Py<PySlice> or Bound<'py, PySlice>.

For APIs available on slice objects, see the PySliceMethods trait which is implemented for Bound<'py, PySlice>.

Only isize indices supported at the moment by the PySlice object.
