Struct BlockConfig 

pub struct BlockConfig {
    pub drive_id: String,
    pub path_on_host: PathBuf,
    pub is_root_device: bool,
    pub is_read_only: bool,

Block-device configuration.

Fields

drive_id: String

Operator-supplied identifier — surfaces via VIRTIO_BLK_T_GET_ID.

path_on_host: PathBuf

Path to the host-side backing file.

is_root_device: bool

true if the drive is the root device (informational; no behavior).

is_read_only: bool

true opens the backing file read-only and offers VIRTIO_BLK_F_RO.

cache_type: CacheType

Unsafe (no flush) or Writeback (flush honored).

partuuid: Option<String>

PARTUUID, threaded into the FDT boot_args if is_root_device.
