WebA simple bitwise copy of String values would merely copy the pointer, leading to a double free down the line. For this reason, String is Clone but not Copy. Clone is a supertrait of Copy, so everything which is Copy must also implement Clone. If a type is Copy then its Clone implementation only needs to return *self (see the example above).

WebIf an object has a destructor then it has move semantics. If it does not, then all of its fields are examined and if any of those do then the whole object has move semantics. And so on down the object structure. If no destructors are found anywhere in an object, then it has copy semantics. WebJul 22, 2005 · bitwise copy for primitives (including pointers) and for objects types call their default constructor. Default copy constructor is a bit confusing terminology. I prefer "implicitly defined" or "compiler generated' constructor. The implicitly defined copy constructor invokes the copy constructor (not the default) to copy all the subobjects.

WebNov 28, 2024 · But if the class exhibits "Bitwise Copy Semantics" (Lippman, p. 43) then the compiler does not have to synthesize a copy constructor (which would result in a function call, possibly inlined) and do bitwise copy instead. This claim is apparently backed up in the ARM, but I haven't looked this up yet.
