Struct aws_sdk_emr::model::Tag

#[non_exhaustive]
pub struct Tag {
    pub key: Option<String>,
    pub value: Option<String>,
}

A key-value pair containing user-defined metadata that you can associate with an Amazon EMR resource. Tags make it easier to associate clusters in various ways, such as grouping clusters to track your Amazon EMR resource allocation costs. For more information, see Tag Clusters.

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.

key: Option<String>

A user-defined key, which is the minimum required information for a valid tag. For more information, see Tag .

value: Option<String>

A user-defined value, which is optional in a tag. For more information, see Tag Clusters.

Implementations

impl Tag

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