#[non_exhaustive]pub enum XavcHdProfileTelecine {
Hard,
None,
Unknown(UnknownVariantValue),
}
Expand description
When writing a match expression against XavcHdProfileTelecine
, 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 xavchdprofiletelecine = unimplemented!();
match xavchdprofiletelecine {
XavcHdProfileTelecine::Hard => { /* ... */ },
XavcHdProfileTelecine::None => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when xavchdprofiletelecine
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant XavcHdProfileTelecine::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
XavcHdProfileTelecine::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 XavcHdProfileTelecine::NewFeature
is defined.
Specifically, when xavchdprofiletelecine
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on XavcHdProfileTelecine::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. Ignore this setting unless you set Frame rate (framerateNumerator divided by framerateDenominator) to 29.970. If your input framerate is 23.976, choose Hard. Otherwise, keep the default value None. For more information, see https://docs.aws.amazon.com/mediaconvert/latest/ug/working-with-telecine-and-inverse-telecine.html.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Hard
None
Unknown(UnknownVariantValue)
Unknown
. See the docs on this enum for the correct way to handle unknown variants.Unknown
contains new variants that have been added since this code was generated.
