Struct openstack::compute::BlockDevice

#[non_exhaustive]pub struct BlockDevice {
    pub boot_index: Option<u16>,
    pub delete_on_termination: bool,
    pub destination_type: BlockDeviceDestinationType,
    pub guest_format: Option<String>,
    pub size_gib: Option<u32>,
    pub source: Option<BlockDeviceSource>,
}

A block device to attach to a server.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

boot_index: Option<u16>

Boot index of the device if it's intended to be bootable.

Note

Not all backends support values other than None and Some(0).

delete_on_termination: bool

Whether to delete the created volume on termination (defaults to false).

destination_type: BlockDeviceDestinationType

A type of the destination: local disk or persistent volume.

guest_format: Option<String>

Format of the target device if it needs to be formatted.

size_gib: Option<u32>

The size (in GiB) of the created volume (if any).

Note

This is only mandatory when creating source is None.

source: Option<BlockDeviceSource>

A source for this block device (if any).

Implementations

impl BlockDevice

pub fn new(
    source: BlockDeviceSource,
    destination_type: BlockDeviceDestinationType
) -> BlockDevice

Create a block device from the specified source.

pub fn swap(size_gib: u32) -> BlockDevice

Create a swap device.

pub fn from_image<I>(image: I) -> BlockDevice where
    I: Into<ImageRef>, 

Attach an image.

This is used for the entry referring to the image that the instance is being booted with. Boot index 0 is used for it.

Use from_new_volume to create a volume from any image.

pub fn from_volume<V>(volume: V, is_boot_device: bool) -> BlockDevice where
    V: Into<VolumeRef>, 

Attach a remote volume.

The volume will be the first bootable device if is_boot_device is true.

pub fn from_empty_volume(size_gib: u32) -> BlockDevice

Create a new empty volume.

pub fn from_new_volume<I>(
    image: I,
    size_gib: u32,
    is_boot_device: bool
) -> BlockDevice where
    I: Into<ImageRef>, 

Create a volume from an image.

The volume will be the first bootable device if is_boot_device is true.

Trait Implementations

impl Clone for BlockDevice

fn clone(&self) -> BlockDevice

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlockDevice

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Serialize for BlockDevice

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.
