Instance members
var baseAddress: UnsafeMutablePointer<Element>?
A pointer to the first element of the buffer.
let count: Int
The number of elements in the buffer.
var debugDescription: String
A textual representation of the buffer, suitable for debugging.
var endIndex: Int
The “past the end” position—that is, the position one greater than the last valid subscript argument.
var indices: UnsafeMutableBufferPointer<Element>.Indices
var isEmpty: Bool
A Boolean value indicating whether the buffer is empty.
var startIndex: Int
The index of the first element in a nonempty buffer.
subscript(Int
) -> Element Accesses the element at the specified position.
subscript(Range<Int>
) -> Slice<UnsafeMutableBufferPointer<Element>> Accesses a contiguous subrange of the buffer’s elements.
subscript(Int
) -> Element Accesses the element at the specified position.

) Deinitializes the memory underlying the element at
index
