NAME

std::execution::just_error - std::execution::just_error

Synopsis

Defined in header <execution>
execution::sender auto just_error( auto && error ); (since C++26)

Parameters

error - input error which will be injected and returned by the receiver.

Return value

Returns a sender with no completion schedulers, which sends the provided values.

Notes

If the provided error is an lvalue reference, a copy is made inside the returned
sender and a non-const lvalue reference to the copy is sent to the receiver’s
set_error. If the provided value is an rvalue reference, it is moved into the
returned sender and an rvalue reference to it is sent to the receiver’s set_error.
