Required Associated Types

type Item: Clone

Required Methods

fn do_set(&mut self, index: usize, value: Self::Item)

fn do_delete(&mut self, index: usize)

fn do_set_range(&mut self, range: Range<usize>, items: &[Self::Item])

as CPython, length of range and items could be different, function must act like Vec::splice()

fn do_delete_range(&mut self, range: Range<usize>)

fn do_set_indexes<I>(&mut self, indexes: I, items: &[Self::Item])

where I: Iterator<Item = usize>,

fn do_delete_indexes<I>(&mut self, range: Range<usize>, indexes: I)

where I: Iterator<Item = usize>,

indexes must be positive order

Provided Methods

fn setitem_by_index( &mut self, vm: &VirtualMachine, index: isize, value: Self::Item ) -> PyResult<()>

fn setitem_by_slice_no_resize( &mut self, vm: &VirtualMachine, slice: SaturatedSlice, items: &[Self::Item] ) -> PyResult<()>

fn setitem_by_slice( &mut self, vm: &VirtualMachine, slice: SaturatedSlice, items: &[Self::Item] ) -> PyResult<()>

fn delitem_by_index( &mut self, vm: &VirtualMachine, index: isize ) -> PyResult<()>

fn delitem_by_slice( &mut self, _vm: &VirtualMachine, slice: SaturatedSlice ) -> PyResult<()>
