import Swift

@frozen struct Array<Element>

An ordered, random-access collection.

init()

Creates a new, empty array.

init<S>(_ s: S) where Element == S.Element, S : Sequence

Creates an array containing the elements of a sequence.

init(arrayLiteral elements: Element...)

Creates an array from the given array literal.

init(repeating repeatedValue: Element, count: Int)

Creates a new array containing the specified number of a single, repeated value.

init(unsafeUninitializedCapacity: Int, initializingWith initializer: (inout UnsafeMutableBufferPointer<Element>, inout Int) throws -> Void) rethrows

Creates an array with the specified capacity, then calls the given closure with a buffer covering the array’s uninitialized memory.

var capacity: Int { get }

The total number of elements that the array can contain without allocating new storage.

var count: Int { get }

The number of elements in the array.

var customMirror: Mirror { get }

A mirror that reflects the array.

var debugDescription: String { get }

A textual representation of the array and its elements, suitable for debugging.

var description: String { get }

A textual representation of the array and its elements.

var endIndex: Int { get }

The array’s “past the end” position—that is, the position one greater than the last valid subscript argument.

var startIndex: Int { get }

The position of the first element in a nonempty array.

subscript(bounds: Range<Int>) -> ArraySlice<Element> { get set }

Accesses a contiguous subrange of the array’s elements.

subscript(index: Int) -> Element { get set }

Accesses the element at the specified position.

static func += (lhs: inout Array<Element>, rhs: Array<Element>)

mutating func append(_ newElement: Element)

Adds a new element at the end of the array.

mutating func append<S>(contentsOf newElements: S) where Element == S.Element, S : Sequence

Adds the elements of a sequence to the end of the array.

func distance(from start: Int, to end: Int) -> Int

Returns the distance between two indices.

func formIndex(after i: inout Int)

func formIndex(before i: inout Int)

func index(_ i: Int, offsetBy distance: Int) -> Int

Returns an index that is the specified distance from the given index.

func index(_ i: Int, offsetBy distance: Int, limitedBy limit: Int) -> Int?

Returns an index that is the specified distance from the given index, unless that distance is beyond a given limiting index.

func index(after i: Int) -> Int

Returns the position immediately after the given index.

func index(before i: Int) -> Int

Returns the position immediately before the given index.

mutating func insert(_ newElement: Element, at i: Int)

Inserts a new element at the specified position.

@discardableResult mutating func remove(at index: Int) -> Element

Removes and returns the element at the specified position.

mutating func removeAll(keepingCapacity keepCapacity: Bool = false)

Removes all elements from the array.

mutating func replaceSubrange<C>(_ subrange: Range<Int>, with newElements: C) where Element == C.Element, C : Collection

Replaces a range of elements with the elements in the specified collection.

mutating func reserveCapacity(_ minimumCapacity: Int)

Reserves enough space to store the specified number of elements.

mutating func withContiguousMutableStorageIfAvailable<R>(_ body: (inout UnsafeMutableBufferPointer<Element>) throws -> R) rethrows -> R?

func withContiguousStorageIfAvailable<R>(_ body: (UnsafeBufferPointer<Element>) throws -> R) rethrows -> R?

func withUnsafeBufferPointer<R>(_ body: (UnsafeBufferPointer<Element>) throws -> R) rethrows -> R

Calls a closure with a pointer to the array’s contiguous storage.

func withUnsafeBytes<R>(_ body: (UnsafeRawBufferPointer) throws -> R) rethrows -> R

Calls the given closure with a pointer to the underlying bytes of the array’s contiguous storage.

mutating func withUnsafeMutableBufferPointer<R>(_ body: (inout UnsafeMutableBufferPointer<Element>) throws -> R) rethrows -> R

Calls the given closure with a pointer to the array’s mutable contiguous storage.

mutating func withUnsafeMutableBytes<R>(_ body: (UnsafeMutableRawBufferPointer) throws -> R) rethrows -> R

Calls the given closure with a pointer to the underlying bytes of the array’s mutable contiguous storage.

typealias Index = Int

The index type for arrays, Int.

typealias Indices = Range<Int>

The type that represents the indices that are valid for subscripting an array, in ascending order.

typealias Iterator = IndexingIterator<Array<Element>>

The type that allows iteration over an array’s elements.
