@DoumanAsh @max-frai @brandur would mind checking how painful is to upgrade to actix-web master?

@brandur i noticed you use hyper as http client, did you try actix_web::client? btw would you mind if i translate your blog post to russian and post it on tech website?

@DoumanAsh @max-frai @brandur would mind checking how painful is to upgrade to actix-web master?

Sure! I just timed it and it took me 10 minutes to upgrade. My project had ~50 or so changes required (see https://github.com/brandur/podcore/commit/45caaf2c0bafcf790d46fdbe96ef07d0a7d0ce17 in case it's helpful to someone else).

Some API stabilization would be nice, but I have to say that especially the change to HttpResponseBuilder functions returning HttpResponse is a huge improvement — previously I was a little confused as to what I was supposed to be doing with that Result.

@brandur i noticed you use hyper as http client, did you try actix_web::client?

Not yet. My use of hyper is mostly for historical reasons — basically I was pulling in packages as I needed to do things, and hyper was the predominant HTTP client. I'm not married to it, but I want to make other changes first. I've put trying actix_web::client in my TODO list.

btw would you mind if i translate your blog post to russian and post it on tech website?

Go for it!

@fafhrd91 Well it is certainly a bit bothersome with all these renaming and change in return values for HttpResponse.

Still it is a bit better API thanks to HttpResponseBuilder to return HttpResponse directly instead of old way

[fafhrd91]

@DoumanAsh i'd like to reduce amount api you need to export (api sureface), this takes some time.

note on .body() method. originally i used same approach as http crate. it seemed good. but over time i realized that it is not very ergonomic and also nobody actually check for body error and just return it.

[DoumanAsh]

DefaultHeaders got simplified too while it is breaking change, it is still better API :)
