sbi 159k38206390 I imagine that mentioning the pimpl is as critical as mentioning the duplicate, the swap and also the destruction. The swap just isn't magically exception-safe. It truly is exception-Protected because swapping ideas is exception-Safe and sound. You won't have to utilize a pimpl, but if you don't You then have to Be certain that each swap of the member is exception-safe. Which might be a nightmare when these associates can modify and it can be trivial every time they're concealed guiding a pimpl. And then, then will come the cost of the pimpl. Which sales opportunities us to your summary That usually exception-security bears a value in general performance. – wilhelmtell Dec 22 'ten at fourteen:forty one 5 std::swap(this_string, that) will not offer a no-toss assurance.
