gzip data compression from Swift, OS X & Linux ready

Usage

Works on NSData and C7.Data, or anything Gzippable

let myData = ... //NSData or C7.Data
let myGzipCompressedData = try myData.gzipCompressed() //NSData or C7.Data
...
let myGzipUncompressedData = try myGzipCompressedData.gzipUncompressed() //NSData or C7.Data
... //PROFIT!

Also contains a GzipStream class which conforms to C7.ReceivingStream, so it can be easily attached in a pipeline, like

let gzippedStream = ... //e.g. from S4.Body
let uncompressedStream = try GzipStream(rawStream: gzippedStream, mode: .uncompress)
... //PROFIT!

Also contains a S4 compatible Middleware, which automatically adds the right headers to the request and decompresses the response if it's compressed.

let client = HTTPSClient.Client("https://my.server")
let response = client.get("/compressed", middleware: GzipMiddleware())
response.body.becomeBuffer() //<- Already decompressed data

Details

As this library uses a SwiftPM-compatible source of zlib, you don't need to install anything manually before using it. Even though both OS X and Linux have a preinstalled version of zlib, unfortunately each has a different version, making its potential use inconsistent. In our case everything is compiled from source, so you can be sure to get the same results everywhere. 💯
