struct CircularBuffer<Element>An automatically expanding ring buffer implementation backed by a ContiguousArray. Even though this implementation will automatically expand if more elements than initialCapacity are stored, it’s advantageous to prevent expansions from happening frequently. Expansions will always force an allocation and a copy to happen.
@frozen struct BoolA value type whose instances are either true or false.
init() Allocates an empty buffer.
init(arrayLiteral elements: Element...) init(initialCapacity: Int) Allocates a buffer that can hold up to initialCapacity elements and initialise an empty ring backed by the buffer. When the ring grows to more than initialCapacity elements the buffer will be expanded.
var capacity: Int { get }The total number of elements that the ring can contain without allocating new storage.
var count: Int { get }Returns the number of element in the ring.
var description: String { get }Returns a human readable description of the ring.
var endIndex: Index { get }The CircularBuffer’s “past the end” position—that is, the position one greater than the last valid subscript argument.
var first: Element? { get }The first Element of the CircularBuffer (or nil if empty).
var isEmpty: Bool { get }Returns whether the ring is empty.
var startIndex: Index { get }The position of the first element in a nonempty CircularBuffer.
subscript(bounds: Range<Index>) -> SubSequence { get set } subscript(position: Index) -> Element { get set } Accesses the element at the specified index.
subscript(offset offset: Int) -> Element { get set } Return element offset from first element.

func distance(from start: CircularBuffer<Element>.Index, to end: CircularBuffer<Element>.Index) -> Int func index(_ i: Index, offsetBy distance: Int) -> Index Returns the index offset by distance from index.
func index(after: Index) -> Index Returns the position immediately after the given index.
func index(before: Index) -> Index Returns the index before index.
mutating func modify<Result>(_ index: Index, _ modifyFunc: (inout Element) throws -> Result) rethrows -> Result Modify the element at index.
mutating func popFirst() -> Element? Removes and returns the first element of the CircularBuffer.
mutating func popLast() -> Element? Removes and returns the last element of the CircularBuffer.
mutating func prepend(_ value: Element) Prepend an element to the front of the ring buffer.
@discardableResult mutating func remove(at position: Index) -> Element Removes & returns the item at position from the buffer
@discardableResult mutating func removeFirst() -> Element Removes and returns the first element of the CircularBuffer.
mutating func removeFirst(_ k: Int) Removes the specified number of elements from the beginning of the CircularBuffer.
@discardableResult mutating func removeLast() -> Element Removes and returns the last element of the CircularBuffer.
mutating func removeLast(_ k: Int) Removes the specified number of elements from the end of the CircularBuffer.
mutating func removeSubrange(_ bounds: Range<Index>) Removes the elements in the specified subrange from the circular buffer.
mutating func replaceSubrange<C>(_ subrange: Range<Index>, with newElements: C) where Element == C.Element, C : Collection Replaces the specified subrange of elements with the given CircularBuffer.
mutating func reserveCapacity(_ minimumCapacity: Int) Prepares the CircularBuffer to store the specified number of elements.
