Expand description
When writing a match expression against Icon
, 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 icon = unimplemented!();
match icon {
Icon::ArrowDown => { /* ... */ },
Icon::ArrowDownLeft => { /* ... */ },
Icon::ArrowDownRight => { /* ... */ },
Icon::ArrowLeft => { /* ... */ },
Icon::ArrowRight => { /* ... */ },
Icon::ArrowUp => { /* ... */ },
Icon::ArrowUpLeft => { /* ... */ },
Icon::ArrowUpRight => { /* ... */ },
Icon::CaretDown => { /* ... */ },
Icon::CaretUp => { /* ... */ },
Icon::Checkmark => { /* ... */ },
Icon::Circle => { /* ... */ },
Icon::FaceDown => { /* ... */ },
Icon::FaceFlat => { /* ... */ },
Icon::FaceUp => { /* ... */ },
Icon::Flag => { /* ... */ },
Icon::Minus => { /* ... */ },
Icon::OneBar => { /* ... */ },
Icon::Plus => { /* ... */ },
Icon::Square => { /* ... */ },
Icon::ThreeBar => { /* ... */ },
Icon::ThumbsDown => { /* ... */ },
Icon::ThumbsUp => { /* ... */ },
Icon::Triangle => { /* ... */ },
Icon::TwoBar => { /* ... */ },
Icon::X => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when icon
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant Icon::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
Icon::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 Icon::NewFeature
is defined.
Specifically, when icon
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on Icon::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.
