VkMemoryDecompressionMethodFlagBitsEXT(3)

# VkMemoryDecompressionMethodFlagBitsEXT(3) Manual Page

## Name

VkMemoryDecompressionMethodFlagBitsEXT - List the supported memory decompression methods

## C Specification

Bits which can be set in `VkDecompressMemoryRegionEXT`::`decompressionMethod` or `VkDecompressMemoryRegionNV`::`decompressionMethod` specifying the decompression method to select, or returned in `VkPhysicalDeviceMemoryDecompressionPropertiesEXT`::`decompressionMethods` specifying the available decompression methods are:

    // Provided by VK_EXT_memory_decompression
    // Flag bits for VkMemoryDecompressionMethodFlagBitsEXT
    typedef VkFlags64 VkMemoryDecompressionMethodFlagBitsEXT;
    static const VkMemoryDecompressionMethodFlagBitsEXT VK_MEMORY_DECOMPRESSION_METHOD_GDEFLATE_1_0_BIT_EXT = 0x00000001ULL;
    static const VkMemoryDecompressionMethodFlagBitsEXT VK_MEMORY_DECOMPRESSION_METHOD_GDEFLATE_1_0_BIT_NV = 0x00000001ULL;

    // Provided by VK_NV_memory_decompression
    // Equivalent to VkMemoryDecompressionMethodFlagBitsEXT
    typedef VkMemoryDecompressionMethodFlagBitsEXT VkMemoryDecompressionMethodFlagBitsNV;

## Description

- VK_MEMORY_DECOMPRESSION_METHOD_GDEFLATE_1_0_BIT_EXT specifies that the GDeflate 1.0 algorithm is used to decompress data.
