cpp/named req/CopyAssignable

Specifies that an instance of the type can be copy-assigned (copied).

This concept implies Template:concept.

Requirements

The type must implement the following functions:

Type::operator=

Type& Type::operator=( Type& other ); Type& Type::operator=( const Type& other ); Type& Type::operator=( volatile Type& other ); Type& Type::operator=( const volatile Type& other );		(One of the variants is sufficient)

Copy assignment operator: assigns the contents of other. The internal state of other must not be modified.

The following expressions must have the specified effects:

Expression	Effects
a = v;	a is equivalent to v, where a is an instance of Type and v is an instance of Type. v must be unchanged.
