Crate disk

VM disk image file format I/O.

Modules

• android_sparse 🔒
• asynchronous 🔒
  Asynchronous disk image helpers.
• composite 🔒
• gpt 🔒
  Functions for writing GUID Partition Tables for use in a composite disk image.
• qcow 🔒
• sys 🔒

Structs

• DiskFileParams
• PartitionInfo
  Information about a partition to create.
• QcowFile
  Represents a qcow2 file. This is a sparse file format maintained by the qemu project. Full documentation of the format can be found in the qemu repository.
• SingleFileDisk
  A disk backed by a single file that implements AsyncDisk for access.

Enums

• CompositeError
• Error
• GptError
• ImagePartitionType
  The type of partition.
• ImageType
  The variants of image files on the host that can be used as virtual disks.

Constants

• MAX_NESTING_DEPTH 🔒
  Nesting depth limit for disk formats that can open other disk files.
• QCOW_MAGIC

Traits

• AsyncDisk
  An asynchronously accessible disk.
• DiskFile
  The prerequisites necessary to support a block device.
• DiskGetLen
  A trait for getting the length of a disk image or raw block device.
• ToAsyncDisk
  A DiskFile that can be converted for asychronous access.

Functions

• create_composite_disk
  Create a new composite disk image containing the given partitions, and write it out to the given files.
• create_zero_filler
  Create a zero filler file which can be used to fill the gaps between partition files. The filler is sized to be big enough to fill the gaps. (1 << PARTITION_SIZE_SHIFT)
• detect_image_type
  Detect the type of an image file by checking for a valid header of the supported formats.
• open_disk_file
  Inspect the image file type and create an appropriate disk file to match it.
