[twitter-dev] how could I know whether a status has been retweeted by me

[hzqtc]

I'm working on a twitter client and I want to take advantage of the
new official retweet. I just want to get the same thing like twitter
web "retweeted by you". But the api doesn't contain any information
for whether a status is retweeted by me. So how can I get to know
this?
Thanks.
