UInt4 is a Swift library that represents a 4-bit unsigned data type.
UInt4 conforms to the same protocols as built-in unsigned integer type (eg. UInt8, UInt16, etc). This means that UInt4 can be worked with as any other UIntX provided by the standard library.
The minimum value that can be represented in a UInt4 is 0.
The maximum value that can be represented in a UInt4 is 15.
The UInt4 library has a comprehensive test suite.
Internally, the bits of the UInt4 are represented in an Int. This means that 64-bits of memory (or 32-bits on 32-bit systems) are used for each UInt4.
Simply add the requirement to your Cartfile:
github "markrenaud/UInt4"
Include the dependency in the depdendencies value of your Package.swift
dependencies: [
.package(url: "https://github.com/markrenaud/UInt4", .upToNextMajor(from: "1.0.0"))
]Next, include the library in your target:
.target(
name: "YourTarget",
dependencies: [
"UInt4"
]
)Import the library.
import UInt4
Use as any other unsigned integer type in Swift.
