Defined in header <stop_token>
class never_stop_token;
 (since C++26)

The never_stop_token class models unstoppable_token that provides static information that a stop is never possible nor requested. It is the default stop token type returned by std::get_stop_token

Member alias templates

Type Definition
callback_type<Callback> /*callback-type*/
where the type is defined as:
struct /*callback-type*/

{
explicit /*callback-type*/ ( never_stop_token,
auto && ) noexcept { }

} ;
(exposition only*)

Member functions

stop_requested
[static]
 indicates that a stop can never be requested
(public static member function)
stop_possible
[static]
 indicates that a stop is not possible
(public static member function)
operator==
 compares two never_stop_token objects
(public member function)

std::never_stop_token::stop_requested

static constexpr bool stop_requested( ) noexcept { return false ; }

Always returns false, indicating that a stop can never be requested.

std::never_stop_token::stop_possible

static constexpr bool stop_possible( ) noexcept { return false ; }

Always returns false, indicating that a stop is not possible.

std::never_stop_token::operator==

bool operator== ( const never_stop_token& ) const = default ;

Two never_stop_token objects always compare equal.
