#[non_exhaustive]
pub struct InstanceTypeSpecification {
    pub instance_type: 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.

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.

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 copy 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

This method tests for self and other values to be equal, and is used by ==.

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.
