Enum aws_sdk_mediapackage::model::AdMarkers

#[non_exhaustive]
pub enum AdMarkers {
    Daterange,
    None,
    Passthrough,
    Scte35Enhanced,
    Unknown(UnknownVariantValue),
}

When writing a match expression against AdMarkers, 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 admarkers = unimplemented!();
match admarkers {
    AdMarkers::Daterange => { /* ... */ },
    AdMarkers::None => { /* ... */ },
    AdMarkers::Passthrough => { /* ... */ },
    AdMarkers::Scte35Enhanced => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

The above code demonstrates that when admarkers represents NewFeature, the execution path will lead to the second last match arm, even though the enum does not contain a variant AdMarkers::NewFeature in the current version of SDK. The reason is that the variable other, created by the @ operator, is bound to AdMarkers::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 AdMarkers::NewFeature is defined. Specifically, when admarkers represents NewFeature, the execution path will hit the second last match arm as before by virtue of calling as_str on AdMarkers::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.

Daterange

None

Passthrough

Scte35Enhanced

Unknown(UnknownVariantValue)

Unknown contains new variants that have been added since this code was generated.
