Overview

A Slice is a Pointer with an associated size.

While a pointer is unsafe because no bound checks are performed when reading from and writing to it, reading from and writing to a slice involve bound checks. In this way, a slice is a safe alternative to Pointer.

A Slice can be created as read-only: trying to write to it will raise. For example the slice of bytes returned by String#to_slice is read-only.
