TMap

Standard Swift dictionaries do not provide deterministic encoding. TMap is a generic dictionary implementation where two TMap's with the same key-value pairs are guaranteed guaranteed to be exactly the same down to the last bit. TMap uses a radix trie to encode the key value information.

TMap is intended to be used functionally, and therefore, all TMap instances are immutable - new TMap instances are returned in functions instead of modified.

All Keys must conform to BinaryEncodable (instead of Hashable), and values must conform to Codable.

Installation

Using Swift Package Manager

Add TMap to Package.swift and the appropriate targets

dependencies: [
.package(url: "https://github.com/pumperknickle/TMap.git", from: "1.0.0")
]

Usage

Importing framework

Use TMap by including it in the imports of your swift file

import Swiftrie

Initialization

Create an empty generic dictionary

let newMap = TMap<String, [[String]]>()

Setting values to keys

When setting values, a new structure is returned with the new key value pair.

let key1 = "foo"
let value1 = [["fooValue"]]
let modifiedMap = newMap.setting(key: key1, value: value1)

Getting the values of keys

let key1 = "foo"
let value = newMap[key1]

Deleting keys

let key1 = "foo"
let modifiedMap = deleting(key: key1)
