Typealiases

• typealias Distance

  A type that represents the distance between two pointers.

Type members

• init(UnsafeMutablePointer<Pointee>)

  Creates a mutable typed pointer referencing the same memory as the given mutable pointer.

• init?(UnsafeMutablePointer<Pointee>?)

  Creates a mutable typed pointer referencing the same memory as the given mutable pointer.

• init?(mutating: UnsafePointer<Pointee>?)

  Creates a mutable typed pointer referencing the same memory as the given immutable pointer.

• static func allocate(capacity: Int) -> UnsafeMutablePointer<Pointee>

  Allocates uninitialized memory for the specified number of instances of type Pointee.

Instance members

• var hashValue: Int
• var pointee: Pointee

  Reads or updates the instance referenced by this pointer.

• subscript(Int) -> Pointee

  Reads or updates the pointee at the specified offset from this pointer.

• func deallocate()

  Deallocates the memory block previously allocated at this pointer.

• func deinitialize(count: Int) -> UnsafeMutableRawPointer

  Deinitializes the specified number of values starting at this pointer.

• func initialize(from: UnsafePointer<Pointee>, count: Int)

  Initializes the memory referenced by this pointer with the values starting at the given pointer.

• func initialize(repeating: Pointee, count: Int)

  Initializes this pointer’s memory with the specified number of consecutive copies of the given value.

• func initialize(to: consuming Pointee)

  Initializes this pointer’s memory with a single instance of the given value.

• func move() -> Pointee

  Retrieves and returns the referenced instance, returning the pointer’s memory to an uninitialized state.

• func moveInitialize(from: UnsafeMutablePointer<Pointee>, count: Int)

  Moves instances from initialized source memory into the uninitialized memory referenced by this pointer, leaving the source memory uninitialized and the memory referenced by this pointer initialized.

• func moveUpdate(from: UnsafeMutablePointer<Pointee>, count: Int)

  Update this pointer’s initialized memory by moving the specified number of instances the source pointer’s memory, leaving the source memory uninitialized.

• func pointer<Property>(to: KeyPath<Pointee, Property>) -> UnsafePointer<Property>?

  Obtain a pointer to the stored property referred to by a key path.

• func pointer<Property>(to: WritableKeyPath<Pointee, Property>) -> UnsafeMutablePointer<Property>?

  Obtain a mutable pointer to the stored property referred to by a key path.

• func update(from: UnsafePointer<Pointee>, count: Int)

  Update this pointer’s initialized memory with the specified number of instances, copied from the given pointer’s memory.

• func update(repeating: Pointee, count: Int)

  Update this pointer’s initialized memory with the specified number of consecutive copies of the given value.

• func withMemoryRebound<T, E, Result>(to: T.Type, capacity: Int, (UnsafeMutablePointer<T>)throws

  Executes the given closure while temporarily binding memory to the specified number of instances of the given type.
