Function oauth1_request::to_uri_query

pub fn to_uri_query<R: ?Sized>(uri: String, request: &R) -> String where
    R: Request, 

Turns a Request to a query string and appends it to the given URI.

This function naively concatenates a query string to uri and if uri already has a query part, it will have a duplicate query part like ?foo=bar?baz=qux.
