#[non_exhaustive]pub enum HdrToSdrToneMapper {
PreserveDetails,
Vibrant,
Unknown(UnknownVariantValue),
}
Expand description
When writing a match expression against HdrToSdrToneMapper
, 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 hdrtosdrtonemapper = unimplemented!();
match hdrtosdrtonemapper {
HdrToSdrToneMapper::PreserveDetails => { /* ... */ },
HdrToSdrToneMapper::Vibrant => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when hdrtosdrtonemapper
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant HdrToSdrToneMapper::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
HdrToSdrToneMapper::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 HdrToSdrToneMapper::NewFeature
is defined.
Specifically, when hdrtosdrtonemapper
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on HdrToSdrToneMapper::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 how MediaConvert maps brightness and colors from your HDR input to your SDR output. The mode that you select represents a creative choice, with different tradeoffs in the details and tones of your output. To maintain details in bright or saturated areas of your output: Choose Preserve details. For some sources, your SDR output may look less bright and less saturated when compared to your HDR source. MediaConvert automatically applies this mode for HLG sources, regardless of your choice. For a bright and saturated output: Choose Vibrant. We recommend that you choose this mode when any of your source content is HDR10, and for the best results when it is mastered for 1000 nits. You may notice loss of details in bright or saturated areas of your output. HDR to SDR tone mapping has no effect when your input is SDR.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
PreserveDetails
Vibrant
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.
