Webis_nothrow_move_constructible Trait class that identifies whether T is a move constructible type, and such construction is known not to throw any exception. This class inherits from integral_constant as being either true_type or false_type. Template parameters T A complete type, or void (possible cv-qualified), or an array of unknown bound. WebSuch behavior can be used as a performance optimization for move constructors not currently marked noexcept; such move operations can be allowed to fail directly due to allocation failures. Within Abseil code, these direct allocation failures are enabled with the Abseil build-time configuration macro ABSL_ALLOCATOR_NOTHROW.
