#[non_exhaustive]pub enum DvbSubtitleStylePassthrough {
Disabled,
Enabled,
Unknown(UnknownVariantValue),
}
Expand description
When writing a match expression against DvbSubtitleStylePassthrough
, 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 dvbsubtitlestylepassthrough = unimplemented!();
match dvbsubtitlestylepassthrough {
DvbSubtitleStylePassthrough::Disabled => { /* ... */ },
DvbSubtitleStylePassthrough::Enabled => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when dvbsubtitlestylepassthrough
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant DvbSubtitleStylePassthrough::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
DvbSubtitleStylePassthrough::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 DvbSubtitleStylePassthrough::NewFeature
is defined.
Specifically, when dvbsubtitlestylepassthrough
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on DvbSubtitleStylePassthrough::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. To use the available style, color, and position information from your input captions: Set Style passthrough to Enabled. Note that MediaConvert uses default settings for any missing style or position information in your input captions To ignore the style and position information from your input captions and use default settings: Leave blank or keep the default value, Disabled. Default settings include white text with black outlining, bottom-center positioning, and automatic sizing. Whether you set Style passthrough to enabled or not, you can also choose to manually override any of the individual style and position settings. You can also override any fonts by manually specifying custom font files.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Disabled
Enabled
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.
