# ManagedBuffer A class whose instances contain a property of type `Header` and raw storage for an array of `Element`, whose size is determined at instance creation. ``` class ManagedBuffer where Element : ~Copyable ``` ## Overview Note that the `Element` array is suitably-aligned **raw memory**. You are expected to construct and—if necessary—destroy objects there yourself, using the APIs on `UnsafeMutablePointer`. Typical usage stores a count and capacity in `Header` and destroys any live elements in the `deinit` of a subclass. > Note: Subclasses must not have any stored properties; any storage > needed should be included in `Header`. --- Copyright © 2026 Apple Inc.
