Struct PlacementGroupConfig 

pub struct PlacementGroupConfig {
    pub instance_role: String,
    pub placement_strategy: Option<String>,
}

Placement group configuration for an Amazon EMR cluster. The configuration specifies the placement strategy that can be applied to instance roles during cluster creation.

To use this configuration, consider attaching managed policy AmazonElasticMapReducePlacementGroupPolicy to the EMR role.

Starting with Amazon EMR version 5.23.0, the only supported instance role is MASTER.

placement_strategy: Option<String>

impl<'de> Deserialize<'de> for PlacementGroupConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,
