A read-only view on a Rust &str. The contents are guaranteed to be valid
UTF-8. As an additional guarantee on top of Rust's normal UTF-8 guarantee,
a rustls_str is guaranteed not to contain internal NUL bytes, so it is
safe to interpolate into a C string or compare using strncmp. Keep in mind
that it is not NUL-terminated.
The memory exposed is available as specified by the function
using this in its signature. For instance, when this is a parameter to a
callback, the lifetime will usually be the duration of the callback.
Functions that receive one of these must not dereference the data pointer
beyond the allowed lifetime.
