sbi 158k38205389 I feel that mentioning the pimpl is as significant as mentioning the copy, the swap along with the destruction. The swap is just not magically exception-Harmless. It really is exception-Protected simply because swapping pointers is exception-Secure. You won't have to make use of a pimpl, but if you don't Then you definately need to Guantee that each swap of a member is exception-safe. That can be a nightmare when these associates can alter and it really is trivial if they're concealed behind a pimpl. After which you can, then arrives the price of the pimpl. Which potential customers us into the conclusion That usually exception-security bears a price in general performance. – wilhelmtell Dec 22 'ten at fourteen:41 Continue 5 std::swap(this_string, that) won't supply a no-throw assure. It provides robust exception security, but not a no-toss ensure.
