Enum aws_sdk_outposts::types::UplinkGbps
source · #[non_exhaustive]pub enum UplinkGbps {
Uplink100G,
Uplink10G,
Uplink1G,
Uplink40G,
Unknown(UnknownVariantValue),
}Expand description
When writing a match expression against UplinkGbps, 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 uplinkgbps = unimplemented!();
match uplinkgbps {
UplinkGbps::Uplink100G => { /* ... */ },
UplinkGbps::Uplink10G => { /* ... */ },
UplinkGbps::Uplink1G => { /* ... */ },
UplinkGbps::Uplink40G => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when uplinkgbps represents
NewFeature, the execution path will lead to the second last match arm,
even though the enum does not contain a variant UplinkGbps::NewFeature
in the current version of SDK. The reason is that the variable other,
created by the @ operator, is bound to
UplinkGbps::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 UplinkGbps::NewFeature is defined.
Specifically, when uplinkgbps represents NewFeature,
the execution path will hit the second last match arm as before by virtue of
calling as_str on UplinkGbps::NewFeature also yielding "NewFeature".
Explicitly matching on the Unknown variant should
be avoided for two reasons:
- The inner data
UnknownVariantValueis opaque, and no further information can be extracted. - It might inadvertently shadow other intended match arms.
