## Description

This extension allows layered implementations such as ANGLE to modify the default behavior of VkPipelineCache to return only the incremental data from the previous call to vkGetPipelineCacheData. Application developers should avoid using this extension.

Note | There is currently no specification language written for this extension. The links to APIs defined by the extension are to stubs that only include generated content such as API declarations and implicit valid usage statements.

Note | This extension is only intended for use in specific embedded environments with known implementation details, and is therefore undocumented.
