Is it possible to append query values?

[mainrs]

I read through the docs but couldn't find any information on how to append query values to my request. In my case, these are conditional, so some methods on the Builder struct would be great.

Sadly, simply appending them to the URL is not enough. The values have to be URL-encoded. A utility method similar to other crates would be great. It could take any T: Serializable and append the query values. reqwest and ureq provide this IIRC.

Thanks for the great library!

Thanks, we'd love to have this functionality. Would you be up for making a PR? Otherwise it may take a little while until I get around to it.
