Detailed Description

Like std::string_view, but with the extra guarantee that it refers to a zero-terminated string.

In other words it has this additional invariant: data()[size()] == '\0'

Current version only implements a subset of the std::string_view API. That is because:

• Some functions cannot be implemented (those that trim the tail).
• Most were not yet required. We can implement those on demand.
