There's also fromStringz that Jakob suggests using elsewhere in

return cString ? cString[0 .. strlen(cString)] : null;
So, using that over simply slicing is primarily for
documentation purposes, though it does make it so that you
don't have to call strlen directly or check for null before
calling it.
To add to this, the main motivation behind `fromStringz` is that
`cString` is often a non-trivial expression, such as a function
call. With `fromStringz`, this expression can always be put in
the argument list and it will only be evaluated once. Otherwise a
variable has to be added:
auto cString = foo();
return cString[0 .. strlen(cString)];
