PackStream implementation in Swift
PackStream is a binary message format very similar to MessagePack. It can be used stand-alone, but it has been built as a message format for use in the Bolt protocol to communicate between the Neo4j server and its clients.
Through PackStream you can encode Bool, Int, Float (Double in Swift lingo), String, List, Map and Structure. They all implement the
PackProtocol, so if you want to have a collection of packable items, you can specify them as implementing PackProtocol.
First, remember to
Then you can use it, like for instance so:
let map = Map(dictionary: [ "alpha": 42, "beta": 39.3, "gamma": "☺", "delta": List(items: [1,2,3,4]) ]) let result = try map.pack() let restored = try Map.unpack(result)
A list of the numbers 1 to 40
let items = Array(Int8(1)...Int8(40)) let value = List(items: items)
gets encoded to the following bytes
To use directly with Xcode, type "swift package generate-xcodeproj"
Add the following to your dependencies array in Package.swift:
.Package(url: "https://github.com/niklassaers/PackStream-swift.git", majorVersion: 0),
and you can now do a
to your Podfile, and you can now do
to have PackStream included in your Xcode project via CocoaPods
in your Cartfile. If this is your entire Cartfile, do
If you have already done that, do
cd Carthage/Checkouts/PackStream-swift swift package generate-xcodeproj cd -
And Carthage is now set up. You can now do
and you should find a build for macOS, iOS, tvOS and watchOS in Carthage/Build
