#[non_exhaustive]pub enum BurninSubtitleApplyFontColor {
AllText,
WhiteTextOnly,
Unknown(UnknownVariantValue),
}
Expand description
When writing a match expression against BurninSubtitleApplyFontColor
, 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 burninsubtitleapplyfontcolor = unimplemented!();
match burninsubtitleapplyfontcolor {
BurninSubtitleApplyFontColor::AllText => { /* ... */ },
BurninSubtitleApplyFontColor::WhiteTextOnly => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when burninsubtitleapplyfontcolor
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant BurninSubtitleApplyFontColor::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
BurninSubtitleApplyFontColor::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 BurninSubtitleApplyFontColor::NewFeature
is defined.
Specifically, when burninsubtitleapplyfontcolor
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on BurninSubtitleApplyFontColor::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 Style passthrough is set to Enabled and Font color set to Black, Yellow, Red, Green, Blue, or Hex. Use Apply font color for additional font color controls. When you choose White text only, or leave blank, your font color setting only applies to white text in your input captions. For example, if your font color setting is Yellow, and your input captions have red and white text, your output captions will have red and yellow text. When you choose ALL_TEXT, your font color setting applies to all of your output captions text.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
AllText
WhiteTextOnly
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.
