Struct aws_sdk_scheduler::model::PlacementStrategy

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

The task placement strategy for a task or service.

Implementations

impl PlacementStrategy

pub fn type(&self) -> Option<&PlacementStrategyType>

The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that is specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory (but still enough to run the task).

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

The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or instanceId, which has the same effect), or any platform or custom attribute that is applied to a container instance, such as attribute:ecs.availability-zone. For the binpack placement strategy, valid values are cpu and memory. For the random placement strategy, this field is not used.

impl PlacementStrategy

pub fn builder() -> Builder

Creates a new builder-style object to manufacture PlacementStrategy.

Trait Implementations

impl Clone for PlacementStrategy

fn clone(&self) -> PlacementStrategy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PlacementStrategy

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

Formats the value using the given formatter.

impl PartialEq<PlacementStrategy> for PlacementStrategy

fn eq(&self, other: &PlacementStrategy) -> 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.
