Enum aws_sdk_omics::types::AnnotationType

#[non_exhaustive]
pub enum AnnotationType {
    ChrPos,
    ChrPosRefAlt,
    ChrStartEndOneBase,
    ChrStartEndRefAltOneBase,
    ChrStartEndRefAltZeroBase,
    ChrStartEndZeroBase,
    Generic,
    Unknown(UnknownVariantValue),
}

When writing a match expression against AnnotationType, 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 annotationtype = unimplemented!();
match annotationtype {
    AnnotationType::ChrPos => { /* ... */ },
    AnnotationType::ChrPosRefAlt => { /* ... */ },
    AnnotationType::ChrStartEndOneBase => { /* ... */ },
    AnnotationType::ChrStartEndRefAltOneBase => { /* ... */ },
    AnnotationType::ChrStartEndRefAltZeroBase => { /* ... */ },
    AnnotationType::ChrStartEndZeroBase => { /* ... */ },
    AnnotationType::Generic => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

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

ChrPos

Contains contig and 1-base position

ChrPosRefAlt

Contains contig, 1-base position, ref and alt allele information

ChrStartEndOneBase

Contains contig, start, and end positions. Coordinates are 1-based

ChrStartEndRefAltOneBase

Contains contig, start, end, ref and alt allele information. Coordinates are 1-based

ChrStartEndRefAltZeroBase

Contains contig, start, end, ref and alt allele information. Coordinates are 0-based

ChrStartEndZeroBase

Contains contig, start, and end positions. Coordinates are 0-based

Generic

Generic text file. No genomic information

Unknown(UnknownVariantValue)

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