#19454
overview
Added a API for asking user multiple questions and get answers, useful for quick fix that need to ask multiple question and get user choice(i.e. import all missing item, choose multiple import crates etc.)
details
Use ShowMessageRequest to send message to user, and get
MessageActionin return.The major impl is in
ask_for_choicefunction and is somewhere twisted as writing async code using callback is certainly very uncomfortable.ask_for_choicesend with a empty request id as can't determine what request id it should belong to.On the
Assistsside, developer basically provide a callback with signature ofdyn FnOnce(&mut SourceChangeBuilder, &[usize]) + Send + 'staticto handle what to do after get user choices results, so it's similar toadd_groupmethodtodo
test this with a integration test
