#[non_exhaustive]pub enum H265DynamicSubGop {
Adaptive,
Static,
Unknown(UnknownVariantValue),
}
Expand description
When writing a match expression against H265DynamicSubGop
, 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 h265dynamicsubgop = unimplemented!();
match h265dynamicsubgop {
H265DynamicSubGop::Adaptive => { /* ... */ },
H265DynamicSubGop::Static => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when h265dynamicsubgop
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant H265DynamicSubGop::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
H265DynamicSubGop::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 H265DynamicSubGop::NewFeature
is defined.
Specifically, when h265dynamicsubgop
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on H265DynamicSubGop::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 Adaptive to improve subjective video quality for high-motion content. This will cause the service to use fewer B-frames (which infer information based on other frames) for high-motion portions of the video and more B-frames for low-motion portions. The maximum number of B-frames is limited by the value you provide for the setting B frames between reference frames.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Adaptive
Static
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.
