Expand description
When writing a match expression against AntiAlias
, 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 antialias = unimplemented!();
match antialias {
AntiAlias::Disabled => { /* ... */ },
AntiAlias::Enabled => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when antialias
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant AntiAlias::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
AntiAlias::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 AntiAlias::NewFeature
is defined.
Specifically, when antialias
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on AntiAlias::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. The anti-alias filter is automatically applied to all outputs. The service no longer accepts the value DISABLED for AntiAlias. If you specify that in your job, the service will ignore the setting.
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.
