bachand/SomethingTypes

Types that are guaranteed to contain something.

SomethingTypes

SomethingArray define away the empty case with a compile-time guarantee that "something" always exists in the array.

var array = SomethingArray<Int>.seed(1)
print(array) // [1]
array.append(2)
print(array) // [1,2]

It is possible to create a SomethingArray from a standard array, but the result is an optional.

print(SomethingArray([4,5,6])) // Optional([4,5,6])
print(SomethingArray<Int>([])) // nil

static func append(_:) is an alias for static func seed(_:) that enables a homogenous code.

var array = SomethingArray.append("a")
array.append("b")
array.append("c")
print(array) // ["a","b","c"]
