Bits

The bits package is included in Vapor by default and provides a convenient API for working with bytes.

!!! note Use import Bits to use this package.

Typealias

The bits package provides two type-alises for bytes.

typealias Byte = UInt8
typealias Bytes = [Byte]

Converting from bytes to string using the UTF-8 encoding is easy.

let bytes = "hello".makeBytes()
let string = bytes.makeString()
print(string) // "hello"

The upper and lowercase latin alphabet and some additional control characters are statically typed on the Byte.

let bytes: Bytes = [.h, .e, .l, .l, .o]
print(bytes.makeString()) // "hello"

This makes byte manipulation and comparison easy and is useful for building things like parsers and serializers.

let byte: Byte = 65
if byte == .A {
	print("found A!")
}
