Defined in header
<stop_token>
template< class Token >
(since C++26)
concept unstoppable_token =
std::stoppable_token<Token> &&
requires (const Token tok) {
requires std::bool_constant <(!tok.stop_possible())>::value;
The concept unstoppable_token<Token> specifies an additional requirement for a stoppable_token where the type does not allow stopping. That is, the expression tok.stop_possible() must be usable in constant expression and returns false.
