Struct InstanceTypeSpecification

#[non_exhaustive]
pub struct InstanceTypeSpecification {
    pub instance_type: Option<String>,
    pub weighted_capacity: Option<i32>,
    pub bid_price: Option<String>,

}

The configuration specification for each instance type in an instance fleet.

The instance fleet configuration is available only in Amazon EMR releases 4.8.0 and later, excluding 5.0.x versions.

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.

instance_type: Option<String>

The Amazon EC2 instance type, for example m3.xlarge.

weighted_capacity: Option<i32>

The number of units that a provisioned instance of this type provides toward fulfilling the target capacities defined in InstanceFleetConfig. Capacity values represent performance characteristics such as vCPUs, memory, or I/O. If not specified, the default value is 1.

bid_price: Option<String>

The bid price for each Amazon EC2 Spot Instance type as defined by InstanceType. Expressed in USD.

bid_price_as_percentage_of_on_demand_price: Option<f64>

The bid price, as a percentage of On-Demand price, for each Amazon EC2 Spot Instance as defined by InstanceType. Expressed as a number (for example, 20 specifies 20%).

configurations: Option<Vec<Configuration>>

A configuration classification that applies when provisioning cluster instances, which can include configurations for applications and software bundled with Amazon EMR.

ebs_block_devices: Option<Vec<EbsBlockDevice>>

The configuration of Amazon Elastic Block Store (Amazon EBS) attached to each instance as defined by InstanceType.

ebs_optimized: Option<bool>

Evaluates to TRUE when the specified InstanceType is EBS-optimized.

custom_ami_id: Option<String>

The custom AMI ID to use for the instance type.

priority: Option<f64>

The priority at which Amazon EMR launches the Amazon EC2 instances with this instance type. Priority starts at 0, which is the highest priority. Amazon EMR considers the highest priority first.

Implementations

impl InstanceTypeSpecification

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

The Amazon EC2 instance type, for example m3.xlarge.

pub fn weighted_capacity(&self) -> Option<i32>

The number of units that a provisioned instance of this type provides toward fulfilling the target capacities defined in InstanceFleetConfig. Capacity values represent performance characteristics such as vCPUs, memory, or I/O. If not specified, the default value is 1.

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

The bid price for each Amazon EC2 Spot Instance type as defined by InstanceType. Expressed in USD.

pub fn bid_price_as_percentage_of_on_demand_price(&self) -> Option<f64>

The bid price, as a percentage of On-Demand price, for each Amazon EC2 Spot Instance as defined by InstanceType. Expressed as a number (for example, 20 specifies 20%).

pub fn configurations(&self) -> &[Configuration]

A configuration classification that applies when provisioning cluster instances, which can include configurations for applications and software bundled with Amazon EMR.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .configurations.is_none().

pub fn ebs_block_devices(&self) -> &[EbsBlockDevice]

The configuration of Amazon Elastic Block Store (Amazon EBS) attached to each instance as defined by InstanceType.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .ebs_block_devices.is_none().

pub fn ebs_optimized(&self) -> Option<bool>

Evaluates to TRUE when the specified InstanceType is EBS-optimized.

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

The custom AMI ID to use for the instance type.

pub fn priority(&self) -> Option<f64>

The priority at which Amazon EMR launches the Amazon EC2 instances with this instance type. Priority starts at 0, which is the highest priority. Amazon EMR considers the highest priority first.

impl InstanceTypeSpecification

pub fn builder() -> InstanceTypeSpecificationBuilder

Creates a new builder-style object to manufacture InstanceTypeSpecification.

Trait Implementations

impl Clone for InstanceTypeSpecification

fn clone(&self) -> InstanceTypeSpecification

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InstanceTypeSpecification

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

Formats the value using the given formatter.

impl PartialEq for InstanceTypeSpecification

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

Tests for self and other values to be equal, and is used by ==.

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

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