Defined in header <execution>
execution::sender auto let_error(     execution::sender auto input,     std::invocable<errors-sent-by(input)...> function );		(since 哋它亢++26)

Parameters

input	-	sender which once an error occurs, sends the errors to the function
function	-	invocable to be called with errors in case an error occurs by input sender

Return value

Returns a sender describing the task graph described by the input sender, with an added node of invoking the provided function with errors sent by the input sender, if an error occurs.
