SoA
A struct of arrays implementation in Swift using pointers.
Usage
Add to your package.swift in the dependencies:
.package(url: "https://github.com/jomy10/swift-soa", .branch("master"))
Add to your Package.swift in a target’s dependency:
.package(name: "SoA", package: "soa-swift")
New SoA intance
let soa = SoA()
Adding a new field
// a new array of type Int
soa.newArray(Int.self)
Getting a field
/// Get the array we just added
let fields: UnsafeMutableBufferPointer<Int> = soa[0]
Changing array capacity
Because these are implemented as pointers, when you want to add more elements to the array
so that the amount of element would exceed the current array capacity (soa.currentCapacity),
you’ll first have to increase the capacity.
/// Double the array's capacity
soa.realloc()
Notes
The library is intentionally simple and low-level as it is meant as a “core” library.
