//!
//! A number of traits add methods that allow you to accomplish tasks with slices.
//! These traits include `ImmutableSlice`, which is defined for `&[T]` types,
//! `MutableSlice`, defined for `&mut [T]` types, and `Slice` and `SliceMut`
//! which are defined for `[T]`.
//! and `MutableSlice`, defined for `&mut [T]` types.
//!
//! An example is the `slice` method which enables slicing syntax `[a..b]` that
//! returns an immutable "view" into a `Vec` or another slice from the index
