# misc-noexcept-move-constructor

The check flags user-defined move constructors and assignment operators not marked with `noexcept` or marked with `noexcept(expr)` where `expr` evaluates to `false` (but is not a `false` literal itself).

Move constructors of all the types used with STL containers, for example, need to be declared `noexcept`. Otherwise STL will choose copy constructors instead. The same is valid for move assignment operations.
