Struct aws_sdk_scheduler::model::PlacementConstraint

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

An object representing a constraint on task placement.

Implementations

impl PlacementConstraint

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

The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.

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

A cluster query language expression to apply to the constraint. You cannot specify an expression if the constraint type is distinctInstance. For more information, see Cluster query language in the Amazon ECS Developer Guide.

impl PlacementConstraint

pub fn builder() -> Builder

Creates a new builder-style object to manufacture PlacementConstraint.

Trait Implementations

impl Clone for PlacementConstraint

fn clone(&self) -> PlacementConstraint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PlacementConstraint

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

Formats the value using the given formatter.

impl PartialEq<PlacementConstraint> for PlacementConstraint

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