Device nodes for partitionable kernel devices, managed by the kernel.

Device nodes for non-partitionable kernel devices, managed by running kpartx to parse the partition table and create device-mapper devices for each partition.

SavedPartitions

Traits

PartTable

A handle to the set of device nodes for individual partitions of a device. Must be held as long as the device nodes are needed; they might be removed upon drop.

Functions

detect_formatted_sector_size

Inspect a buffer from the start of a disk image and return its formatted sector size, if any can be determined.

find_colocated_esps

Find ESP partitions which sit at the same hierarchy level as device.

find_efi_vendor_dir

This is basically a Rust version of: https://github.com/coreos/coreos-assembler/blob/d3c7ec094a02/src/cmd-buildextend-live#L492-L495

find_parent_devices

This is a bit fuzzy, but… this function will return every block device in the parent hierarchy of device capable of containing other partitions. So e.g. parent devices of type “part” doesn’t match, but “disk” and “mpath” does.

get_blkdev_deps

get_blkdev_deps_recursing

get_block_device_size

Get the size of a block device.

get_filesystems_with_label

Returns filesystems with given label. If multiple filesystems with the label have the same UUID, we only return one of them.

get_gpt_size

Get the size of the GPT metadata at the start of the disk.

get_sector_size

Get the logical sector size of a block device.

get_sector_size_for_path

Get the sector size of the block device at a given path.
