Struct aws_sdk_ec2::model::BlockDeviceMapping

#[non_exhaustive]
pub struct BlockDeviceMapping { /* private fields */ }

Describes a block device mapping, which defines the EBS volumes and instance store volumes to attach to an instance at launch.

Implementations

impl BlockDeviceMapping

pub fn device_name(&self) -> Option<&str>

The device name (for example, /dev/sdh or xvdh).

pub fn virtual_name(&self) -> Option<&str>

The virtual device name (ephemeralN). Instance store volumes are numbered starting from 0. An instance type with 2 available instance store volumes can specify mappings for ephemeral0 and ephemeral1. The number of available instance store volumes depends on the instance type. After you connect to the instance, you must mount the volume.

NVMe instance store volumes are automatically enumerated and assigned a device name. Including them in your block device mapping has no effect.

Constraints: For M3 instances, you must specify instance store volumes in the block device mapping for the instance. When you launch an M3 instance, we ignore any instance store volumes specified in the block device mapping for the AMI.

pub fn ebs(&self) -> Option<&EbsBlockDevice>

Parameters used to automatically set up EBS volumes when the instance is launched.

pub fn no_device(&self) -> Option<&str>

To omit the device from the block device mapping, specify an empty string. When this property is specified, the device is removed from the block device mapping regardless of the assigned value.

impl BlockDeviceMapping

pub fn builder() -> Builder

Creates a new builder-style object to manufacture BlockDeviceMapping.

Trait Implementations

impl Clone for BlockDeviceMapping

fn clone(&self) -> BlockDeviceMapping

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlockDeviceMapping

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

Formats the value using the given formatter.

impl PartialEq<BlockDeviceMapping> for BlockDeviceMapping

fn eq(&self, other: &BlockDeviceMapping) -> bool

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
