C++ concepts: CopyAssignable

Specifies that an instance of the type can be copy-assigned from an lvalue expression.

Requirements

The type T satisfies CopyAssignable if.

• The type T satisfies MoveAssignable, and

Given.

• t, a modifiable lvalue expression of type T
• v, an lvalue expression of type T or const T or an rvalue expression of type const T

The following expressions must be valid and have their specified effects.

Expression	Return type	Return value	Post-conditions
t = v	T&	t	The value of t is equivalent to the value of v. The value of v is unchanged.
