Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.instance_type: Option<InstanceType>The instance type.
mac1.metal is not supported as a launch template override.
If you specify InstanceType, you can't specify InstanceRequirements.
max_price: Option<String>The maximum price per unit hour that you are willing to pay for a Spot Instance. We do not recommend using this parameter because it can lead to increased interruptions. If you do not specify this parameter, you will pay the current Spot price.
If you specify a maximum price, your instances will be interrupted more frequently than if you do not specify this parameter.
If you specify a maximum price, it must be more than USD $0.001. Specifying a value below USD $0.001 will result in an InvalidParameterValue error message.
subnet_id: Option<String>The IDs of the subnets in which to launch the instances. Separate multiple subnet IDs using commas (for example, subnet-1234abcdeexample1, subnet-0987cdef6example2). A request of type instant can have only one subnet ID.
availability_zone: Option<String>The Availability Zone in which to launch the instances.
weighted_capacity: Option<f64>The number of units provided by the specified instance type. These are the same units that you chose to set the target capacity in terms of instances, or a performance characteristic such as vCPUs, memory, or I/O.
If the target capacity divided by this value is not a whole number, Amazon EC2 rounds the number of instances to the next whole number. If this value is not specified, the default is 1.
When specifying weights, the price used in the lowest-price and price-capacity-optimized allocation strategies is per unit hour (where the instance price is divided by the specified weight). However, if all the specified weights are above the requested TargetCapacity, resulting in only 1 instance being launched, the price used is per instance hour.
priority: Option<f64>The priority for the launch template override. The highest priority is launched first.
If the On-Demand AllocationStrategy is set to prioritized, EC2 Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity.
If the Spot AllocationStrategy is set to capacity-optimized-prioritized, EC2 Fleet uses priority on a best-effort basis to determine which launch template override to use in fulfilling Spot capacity, but optimizes for capacity first.
Valid values are whole numbers starting at 0. The lower the number, the higher the priority. If no number is set, the launch template override has the lowest priority. You can set the same priority for different launch template overrides.
placement: Option<Placement>The location where the instance launched, if applicable.
block_device_mappings: Option<Vec<FleetBlockDeviceMappingRequest>>The block device mappings, which define the EBS volumes and instance store volumes to attach to the instance at launch.
Supported only for fleets of type instant.
For more information, see Block device mappings for volumes on Amazon EC2 instances in the Amazon EC2 User Guide.
instance_requirements: Option<InstanceRequirementsRequest>The attributes for the instance types. When you specify instance attributes, Amazon EC2 will identify instance types with those attributes.
If you specify InstanceRequirements, you can't specify InstanceType.
image_id: Option<String>The ID of the AMI in the format ami-17characters00000.
Alternatively, you can specify a Systems Manager parameter, using one of the following formats. The Systems Manager parameter will resolve to an AMI ID on launch.
To reference a public parameter:
-
resolve:ssm:public-parameter
To reference a parameter stored in the same account:
-
resolve:ssm:parameter-name -
resolve:ssm:parameter-name:version-number -
resolve:ssm:parameter-name:label
To reference a parameter shared from another Amazon Web Services account:
-
resolve:ssm:parameter-ARN -
resolve:ssm:parameter-ARN:version-number -
resolve:ssm:parameter-ARN:label
For more information, see Use a Systems Manager parameter instead of an AMI ID in the Amazon EC2 User Guide.
This parameter is only available for fleets of type instant. For fleets of type maintain and request, you must specify the AMI ID in the launch template.
Implementations§

impl FleetLaunchTemplateOverridesRequest
Sourcepub fn instance_type(&self) -> Option<&InstanceType>
pub fn instance_type(&self) -> Option<&InstanceType>
The instance type.
mac1.metal is not supported as a launch template override.
If you specify InstanceType, you can't specify InstanceRequirements.
Sourcepub fn max_price(&self) -> Option<&str>
pub fn max_price(&self) -> Option<&str>
The maximum price per unit hour that you are willing to pay for a Spot Instance. We do not recommend using this parameter because it can lead to increased interruptions. If you do not specify this parameter, you will pay the current Spot price.
If you specify a maximum price, your instances will be interrupted more frequently than if you do not specify this parameter.
If you specify a maximum price, it must be more than USD $0.001. Specifying a value below USD $0.001 will result in an InvalidParameterValue error message.
Sourcepub fn subnet_id(&self) -> Option<&str>
pub fn subnet_id(&self) -> Option<&str>
The IDs of the subnets in which to launch the instances. Separate multiple subnet IDs using commas (for example, subnet-1234abcdeexample1, subnet-0987cdef6example2). A request of type instant can have only one subnet ID.
Sourcepub fn availability_zone(&self) -> Option<&str>
pub fn availability_zone(&self) -> Option<&str>
The Availability Zone in which to launch the instances.
Sourcepub fn weighted_capacity(&self) -> Option<f64>
pub fn weighted_capacity(&self) -> Option<f64>
The number of units provided by the specified instance type. These are the same units that you chose to set the target capacity in terms of instances, or a performance characteristic such as vCPUs, memory, or I/O.
If the target capacity divided by this value is not a whole number, Amazon EC2 rounds the number of instances to the next whole number. If this value is not specified, the default is 1.
When specifying weights, the price used in the lowest-price and price-capacity-optimized allocation strategies is per unit hour (where the instance price is divided by the specified weight). However, if all the specified weights are above the requested TargetCapacity, resulting in only 1 instance being launched, the price used is per instance hour.
Sourcepub fn priority(&self) -> Option<f64>
pub fn priority(&self) -> Option<f64>
The priority for the launch template override. The highest priority is launched first.
If the On-Demand AllocationStrategy is set to prioritized, EC2 Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity.
If the Spot AllocationStrategy is set to capacity-optimized-prioritized, EC2 Fleet uses priority on a best-effort basis to determine which launch template override to use in fulfilling Spot capacity, but optimizes for capacity first.
Valid values are whole numbers starting at 0. The lower the number, the higher the priority. If no number is set, the launch template override has the lowest priority. You can set the same priority for different launch template overrides.
Sourcepub fn placement(&self) -> Option<&Placement>
pub fn placement(&self) -> Option<&Placement>
The location where the instance launched, if applicable.
Sourcepub fn block_device_mappings(&self) -> &[FleetBlockDeviceMappingRequest]
pub fn block_device_mappings(&self) -> &[FleetBlockDeviceMappingRequest]
The block device mappings, which define the EBS volumes and instance store volumes to attach to the instance at launch.
Supported only for fleets of type instant.
For more information, see Block device mappings for volumes on Amazon EC2 instances in the Amazon EC2 User Guide.
If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .block_device_mappings.is_none().
Sourcepub fn instance_requirements(&self) -> Option<&InstanceRequirementsRequest>
pub fn instance_requirements(&self) -> Option<&InstanceRequirementsRequest>
The attributes for the instance types. When you specify instance attributes, Amazon EC2 will identify instance types with those attributes.
If you specify InstanceRequirements, you can't specify InstanceType.
Sourcepub fn image_id(&self) -> Option<&str>
pub fn image_id(&self) -> Option<&str>
The ID of the AMI in the format ami-17characters00000.
Alternatively, you can specify a Systems Manager parameter, using one of the following formats. The Systems Manager parameter will resolve to an AMI ID on launch.
To reference a public parameter:
-

fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().

fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
