Comment #3 on issue 336 by [email protected]: Support generic string type
http://code.google.com/p/protobuf/issues/detail?id=336
Compare 1, 2 and 3. Which one looks cleaner?
array<char, 20> a();
string s();
vector<char> v();
1. { auto z = a(); b.set_field(z.data(), z.size()); }
2. b.set_field(s());
3. { auto z = v(); b.set_field(z.data(), z.size()); }
and will potentially be broken if the template type has data() and size()
but doesn't work like string.
Maybe you should remove the (const char*) overload too, as it might not be
a null terminated string... ;)
Seriously, what's the chance a developer uses such a class with set_field()
and doesn't get compile errors?
