# CVBufferRepresentable CVBufferRepresentable protocol is a sealed protocol intended to be implemented by the types in CoreVideo framework. This protocol facilitates Swift types that wrap a value of CVBuffer type. ``` protocol CVBufferRepresentable : ~Copyable ``` ## Topics ### Associated Types [`associatedtype Buffer : CVBuffer`](/documentation/CoreVideo/CVBufferRepresentable/Buffer) ### Instance Methods [`func withUnsafeBuffer((Self.Buffer) throws -> sending R) rethrows -> sending R`](/documentation/CoreVideo/CVBufferRepresentable/withUnsafeBuffer(_:)) Access the underlying `Buffer` object. This function should be used to bridge existing code that uses the Buffer type. ## Relationships ### Inherited By [`CVImageBufferRepresentable`](/documentation/CoreVideo/CVImageBufferRepresentable) [`CVPixelBufferRepresentable`](/documentation/CoreVideo/CVPixelBufferRepresentable) ### Conforming Types [`CVReadOnlyPixelBuffer`](/documentation/CoreVideo/CVReadOnlyPixelBuffer) [`CVMutablePixelBuffer`](/documentation/CoreVideo/CVMutablePixelBuffer) --- Copyright © 2026 Apple Inc.
