std::error_code::operator=(3) C++ Standard Libary std::error_code::operator=(3)

NAME

std::error_code::operator= - std::error_code::operator=

Synopsis


template< class ErrorCodeEnum > (1) (since C++11)
error_code& operator=( ErrorCodeEnum e ) noexcept;
error_code& operator=( const error_code& other ) = (2) (since C++11)
default; (implicitly declared)
error_code& operator=( error_code&& other ) = default; (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.


This overload participates in overload resolution only if
std::is_error_code_enum<ErrorCodeEnum>::value is true.
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
