Implement ctl::unique_ptr (#1216) The way unique_ptr is supposed to work is as a purely compile-time check that your raw pointers are getting deleted when they go out of scope. It should ideally emit the same exact machine code as if you were using raw pointers with manual deletes. Part of what this means is that under normal circumstances, a unique_ptr shouldn’t take up more space than a raw pointer - in other words, sizeof unique_ptr<T> should == sizeof(T*). The present PR doesn’t bother with the specialization for array types. I also left a couple other parts of the STL API unimplemented. I’d love to see someone else implement these, or I’ll get to them at some point. 2024-06-16 02:54:52 +00:00			`// -- mode:c++; indent-tabs-mode:nil; c-basic-offset:4; coding:utf-8 --`
