Expand description
When writing a match expression against ParameterExceptionField
, 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 parameterexceptionfield = unimplemented!();
match parameterexceptionfield {
ParameterExceptionField::AcpRuleSetResponseInspection => { /* ... */ },
ParameterExceptionField::AndStatement => { /* ... */ },
ParameterExceptionField::AssociableResource => { /* ... */ },
ParameterExceptionField::AssociatedResourceType => { /* ... */ },
ParameterExceptionField::AtpRuleSetResponseInspection => { /* ... */ },
ParameterExceptionField::BodyParsingFallbackBehavior => { /* ... */ },

ParameterExceptionField::MapMatchScope => { /* ... */ },
ParameterExceptionField::MetricName => { /* ... */ },
ParameterExceptionField::NotStatement => { /* ... */ },
ParameterExceptionField::OrStatement => { /* ... */ },
ParameterExceptionField::OverrideAction => { /* ... */ },

ParameterExceptionField::ResourceArn => { /* ... */ },
ParameterExceptionField::ResourceType => { /* ... */ },
ParameterExceptionField::ResponseContentType => { /* ... */ },
ParameterExceptionField::Rule => { /* ... */ },
ParameterExceptionField::RuleAction => { /* ... */ },
ParameterExceptionField::RuleGroup => { /* ... */ },
ParameterExceptionField::RuleGroupReferenceStatement => { /* ... */ },
ParameterExceptionField::ScopeDown => { /* ... */ },
ParameterExceptionField::ScopeValue => { /* ... */ },
ParameterExceptionField::SingleHeader => { /* ... */ },
ParameterExceptionField::SingleQueryArgument => { /* ... */ },
ParameterExceptionField::SizeConstraintStatement => { /* ... */ },
ParameterExceptionField::SqliMatchStatement => { /* ... */ },
ParameterExceptionField::Statement => { /* ... */ },
ParameterExceptionField::Tags => { /* ... */ },
ParameterExceptionField::TagKeys => { /* ... */ },
ParameterExceptionField::TextTransformation => { /* ... */ },
ParameterExceptionField::TokenDomain => { /* ... */ },
ParameterExceptionField::WebAcl => { /* ... */ },
ParameterExceptionField::XssMatchStatement => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when parameterexceptionfield
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant ParameterExceptionField::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
ParameterExceptionField::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 ParameterExceptionField::NewFeature
is defined.
Specifically, when parameterexceptionfield
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on ParameterExceptionField::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.
