Expand description
When writing a match expression against Eac3AtmosDynamicRangeCompressionRf
, 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 eac3atmosdynamicrangecompressionrf = unimplemented!();
match eac3atmosdynamicrangecompressionrf {
Eac3AtmosDynamicRangeCompressionRf::FilmLight => { /* ... */ },
Eac3AtmosDynamicRangeCompressionRf::FilmStandard => { /* ... */ },
Eac3AtmosDynamicRangeCompressionRf::MusicLight => { /* ... */ },
Eac3AtmosDynamicRangeCompressionRf::MusicStandard => { /* ... */ },
Eac3AtmosDynamicRangeCompressionRf::None => { /* ... */ },
Eac3AtmosDynamicRangeCompressionRf::Speech => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when eac3atmosdynamicrangecompressionrf
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant Eac3AtmosDynamicRangeCompressionRf::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
Eac3AtmosDynamicRangeCompressionRf::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 Eac3AtmosDynamicRangeCompressionRf::NewFeature
is defined.
Specifically, when eac3atmosdynamicrangecompressionrf
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on Eac3AtmosDynamicRangeCompressionRf::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. Choose the Dolby dynamic range control (DRC) profile that MediaConvert uses when encoding the metadata in the Dolby stream for the RF operating mode. Default value: Film light Related setting: To have MediaConvert use the value you specify here, keep the default value, Custom for the setting Dynamic range control. Otherwise, MediaConvert ignores Dynamic range compression RF. For information about the Dolby DRC operating modes and profiles, see the Dynamic Range Control chapter of the Dolby Metadata Guide at https://developer.dolby.com/globalassets/professional/documents/dolby-metadata-guide.pdf.
