struct suspend_always; | (since C++20) | |
suspend_always is an empty class which can be used to indicate that anawait expression always suspends and does not produce a value.

await_ready | indicates that an await expression always suspends (public member function) |

await_resume | no-op (public member function) |
constexprbool await_ready()constnoexcept{returnfalse;} | ||
Always returnsfalse, indicating that an await expression always suspends.
constexprvoid await_suspend(std::coroutine_handle<>)constnoexcept{} | ||
Does nothing.
constexprvoid await_resume()constnoexcept{} | ||
Does nothing. An await expression does not produce a value ifsuspend_always is used.

(C++20) | indicates that an await-expression should never suspend (class)[edit] |
