draft/source/strings.tex

Line 4156 in 70f8c12

For a \tcode{basic_string_view str}, any operation that invalidates a pointer in the range \range{str.data()}{str.data() + str.size()} invalidates pointers, iterators, and references returned from \tcode{str}'s member functions.

The assignment operators return a reference to *this, but *this is not invalidated.

I think the exclusion of *this is not obviously editorial, but will need a nod by LWG.
