#[non_exhaustive]pub enum EmbeddedConvert608To708 {
Disabled,
Upconvert,
Unknown(UnknownVariantValue),
}
Expand description
When writing a match expression against EmbeddedConvert608To708
, 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 embeddedconvert608to708 = unimplemented!();
match embeddedconvert608to708 {
EmbeddedConvert608To708::Disabled => { /* ... */ },
EmbeddedConvert608To708::Upconvert => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when embeddedconvert608to708
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant EmbeddedConvert608To708::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
EmbeddedConvert608To708::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 EmbeddedConvert608To708::NewFeature
is defined.
Specifically, when embeddedconvert608to708
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on EmbeddedConvert608To708::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. Specify whether this set of input captions appears in your outputs in both 608 and 708 format. If you choose Upconvert, MediaConvert includes the captions data in two ways: it passes the 608 data through using the 608 compatibility bytes fields of the 708 wrapper, and it also translates the 608 data into 708.
