Expand description
When writing a match expression against Transferable
, 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 transferable = unimplemented!();
match transferable {
Transferable::DomainInAnotherAccount => { /* ... */ },
Transferable::DomainInOwnAccount => { /* ... */ },
Transferable::DontKnow => { /* ... */ },
Transferable::PremiumDomain => { /* ... */ },
Transferable::Transferable => { /* ... */ },
Transferable::Untransferable => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when transferable
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant Transferable::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
Transferable::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 Transferable::NewFeature
is defined.
Specifically, when transferable
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on Transferable::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.
Whether the domain name can be transferred to Route 53.
You can transfer only domains that have a value of TRANSFERABLE
or
Transferable
.
Valid values:
- TRANSFERABLE
-
The domain name can be transferred to Route 53.
- UNTRANSFERRABLE
-
The domain name can't be transferred to Route 53.
- DONT_KNOW
-
Reserved for future use.
- DOMAIN_IN_OWN_ACCOUNT
-
The domain already exists in the current Amazon Web Services account.
- DOMAIN_IN_ANOTHER_ACCOUNT
-
The domain exists in another Amazon Web Services account.
- PREMIUM_DOMAIN
-
Premium domain transfer is not supported.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
DomainInAnotherAccount
DomainInOwnAccount

Transferable
Untransferable
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.
