From cppreference.com
Specifies that an instance of the type can be assigned from an
argument.
Requirements
The type T satisfies MoveAssignable if
Given
t, a modifiable
of type T,
rv, an
expression of type T.
The following expressions must be valid and have their specified effects.
ExpressionReturn typeReturn valuePost-conditions t=rvT&tIf t and rv do not refer to the same object, the value of t is equivalent to the value of rv before the assignment. The new value of rv is unspecified.
Notes
The type does not have to implement
in order to satisfy this type requirement: a
that takes its parameter by value or as a const Type&, will bind to rvalue argument.
If a MoveAssignable class implements a move assignment operator, it may also implement
to take advantage of the fact that the value of rv after assignment is unspecified.
