  DSTORAGE_SOURCE          Source;
  DSTORAGE_DESTINATION     Destination;
  UINT32                   UncompressedSize;
  UINT64                   CancellationTag;

Members

Options

Combination of decompression and other options for this request.

Source

The source for this request.

Destination

The destination for this request.

UncompressedSize

The uncompressed size in bytes for the destination for this request. If the request is not compressed, then this can be left as 0. Otherwise, this should be equal to the destination size.

If the destination is to memory or buffer, then the destination size should be specified in the corresponding struct (for example, DSTORAGE_DESTINATION_MEMORY). For textures, it's the value of pTotalBytes returned by GetCopyableFootprints. For tiles, it's 64k * number of tiles.

CancellationTag

An arbitrary UINT64 number used for cancellation matching.

Name

Optional name of the request. Used for debugging. If specified, the string should be accessible until the request completes.
