Struct crosvm::crosvm::sys::unix::device_helpers::DiskConfig

pub struct DiskConfig<'a> {
    disk: &'a DiskOption,
    device_tube: Option<Tube>,
}

A one-shot configuration structure for implementing VirtioDeviceBuilder. We cannot do it on DiskOption directly because disk devices can be passed an optional control tube.

Fields

disk: &'a DiskOption

Options for disk creation.

device_tube: Option<Tube>

Optional control tube for the device.

Implementations

impl<'a> DiskConfig<'a>

pub fn new(disk: &'a DiskOption, device_tube: Option<Tube>) -> Self

Trait Implementations

impl<'a> VirtioDeviceBuilder for DiskConfig<'a>

const NAME: &'static str = "block"

Base name of the device, as it will appear in logs.

fn create_virtio_device(
    self,
    protection_type: ProtectionType
) -> Result<Box<dyn VirtioDevice>>

Create a regular virtio device from the configuration and protection_type setting.

fn create_vhost_user_device(
    self,
    keep_rds: &mut Vec<RawDescriptor>
) -> Result<Box<dyn VhostUserDevice>>

Create a device suitable for being run as a vhost-user instance.

fn create_jail(
    &self,
    jail_config: &Option<JailConfig>,
    virtio_transport: VirtioDeviceType
) -> Result<Option<Minijail>>

Create a jail that is suitable to run a device.

fn create_virtio_device_and_jail(
    self,
    protection_type: ProtectionType,
    jail_config: &Option<JailConfig>
) -> Result<VirtioDeviceStub>

Helper method to return a VirtioDeviceStub filled using create_virtio_device and create_jail.
