An old version of hyper was used before (0.8.0), in the process of updating to hyper 0.12.11, found this higher-level replacement/wrapper, reqwest 0.9.4 which is simpler to use than the latest hyper and serves the purpose of a simple HTTP client well
* Begin updating to hyper 0.12.11
https://github.com/iceiix/steven/issues/4#issuecomment-425759778
* Use type variables for hyper::Client
* Fix setting header syntax, Content-Type: application/json, 17->13
* Parse strings into URLs with url.parse::<hyper::Uri>().unwrap()
b20971cb4e/examples/client.rs (L25)
* Use hyper::Request::post() then client.request() since client.post() removed
* wait() on the ResponseFuture to get the Result
* try! to unwrap the Result
* status() is now a method
* Concatenate body chunks unwrap into bytes, then parse JSON from byte slice, instead of from_reader which didn't compile
* Replace send() with wait() on ResponseFuture
* Parse HeaderValue to u64
* Slices implement std::io::Read trait
* Read into_bytes() instead of read_to_end()
* Disable boxed logger for now to workaround 'expected function, found macro'
* Remove unnecessary mutability, warnings
* Hack to parse twice to avoid double move
* Use hyper-rustls pure Rust implementation for TLS for HTTPS in hyper
* Start converting to reqwest: add Protocol::Error and reqwest::Error conversion
* Use reqwest, replacing hyper, in protocol
* Convert resources to use reqwest instead of hyper
* Convert skin download to reqwest, instead of hyper
* Remove hyper
* Revert unnecessary variable name change req/body to reduce diff
* Revert unnecessary whitespace change to reduce diff, align indentation on .
* Fix authenticating to server, wrong method and join URL
