(3) | (since C++11) (implicitly declared) |
1) Replaces the error code and corresponding category with those representing error code enum e.
Equivalent to *this = make_error_code(e), where make_error_code
is only found by argument-dependent lookup
2,3) Implicitly defined copy-assignment operator and move-assignment operator assign the contents of other to *this
Parameters
e | - | error code enum to construct |
other | - | another error code to assign with |
Return value
*this
