When writing a match expression against EsPartitionInstanceType, it is important to ensure your code is forward-compatible. That is, if a match arm handles a case for a feature that is supported by the service but has not been represented as an enum variant in a current version of SDK, your code should continue to work when you upgrade SDK to a future version in which the enum does include a variant for that feature.

Here is an example of how you can make a match expression forward-compatible:

# let espartitioninstancetype = unimplemented!();
match espartitioninstancetype {
    EsPartitionInstanceType::C42xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::C44xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::C48xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::C4LargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::C4XlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::C518xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::C52xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::C54xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::C59xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::C5LargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::C5XlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::D22xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::D24xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::D28xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::D2XlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::I22xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::I2XlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::I316xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::I32xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::I34xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::I38xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::I3LargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::I3XlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M32xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M3LargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M3MediumElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M3XlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M410xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M42xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M44xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M4LargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M4XlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M512xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M52xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M54xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M5LargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::M5XlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R32xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R34xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R38xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R3LargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R3XlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R416xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R42xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R44xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R48xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R4LargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R4XlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R512xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R52xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R54xlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R5LargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::R5XlargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::T2MediumElasticsearch => { /* ... */ },
    EsPartitionInstanceType::T2MicroElasticsearch => { /* ... */ },
    EsPartitionInstanceType::T2SmallElasticsearch => { /* ... */ },
    EsPartitionInstanceType::Ultrawarm1LargeElasticsearch => { /* ... */ },
    EsPartitionInstanceType::Ultrawarm1MediumElasticsearch => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

The above code demonstrates that when espartitioninstancetype represents NewFeature, the execution path will lead to the second last match arm, even though the enum does not contain a variant EsPartitionInstanceType::NewFeature in the current version of SDK. The reason is that the variable other, created by the @ operator, is bound to EsPartitionInstanceType::Unknown(UnknownVariantValue("NewFeature".to_owned())) and calling as_str on it yields "NewFeature". This match expression is forward-compatible when executed with a newer version of SDK where the variant EsPartitionInstanceType::NewFeature is defined. Specifically, when espartitioninstancetype represents NewFeature, the execution path will hit the second last match arm as before by virtue of calling as_str on EsPartitionInstanceType::NewFeature also yielding "NewFeature".

Explicitly matching on the Unknown variant should be avoided for two reasons:

• The inner data UnknownVariantValue is opaque, and no further information can be extracted.
• It might inadvertently shadow other intended match arms.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
