neptune library

AWS Neptune.

Classes

AppConstant<T>
A value the Stack hands to application code as a static const in the generated AppExports file — known when synth runs, so the app compiles against it.
AppExports
Where synth writes the Dart file application code imports: the Stack's constants, as the static const members of <name>Constants, and a typed reader of its Terraform outputs, <name>Outputs.
AttributeRef<T>
Public for sealed pattern matching, but constructor is private — only TfRef.attribute() may construct instances.
AwsNeptuneCluster
Factory wrapper for aws_neptune_cluster.
AwsNeptuneClusterEndpoint
Factory wrapper for aws_neptune_cluster_endpoint.
AwsNeptuneClusterInstance
Factory wrapper for aws_neptune_cluster_instance.
AwsNeptuneClusterParameterGroup
Factory wrapper for aws_neptune_cluster_parameter_group.
AwsNeptuneClusterSnapshot
Factory wrapper for aws_neptune_cluster_snapshot.
AwsNeptuneEventSubscription
Factory wrapper for aws_neptune_event_subscription.
AwsNeptuneGlobalCluster
Factory wrapper for aws_neptune_global_cluster.
AwsNeptuneParameterGroup
Factory wrapper for aws_neptune_parameter_group.
AwsNeptuneSubnetGroup
Factory wrapper for aws_neptune_subnet_group.
DartDefineOutput
An output whose value is the client build's --dart-define file, registered with Stack.addDartDefineOutput.
Data
Base of every user-instantiable Terraform data block.
DataAwsNeptuneEngineVersion
Factory wrapper for aws_neptune_engine_version.
DataAwsNeptuneOrderableDbInstance
Factory wrapper for aws_neptune_orderable_db_instance.
DataRef<T>
Public for sealed pattern matching, but constructor is private — only TfRef.data() may construct instances.
EnvironmentConstant
The AppConstant.fromEnvironment choice.
GcsBackend
terraform { backend "gcs" { ... } } configuration.
IgnoreAllChanges
IgnoreChanges.all.
IgnoreAttributes
IgnoreChanges.of.
IgnoreChanges
What ignore_changes covers: every attribute, or the listed ones.
InvalidDartDefineOutput
An output of Stack.addDartDefineOutput that cannot carry what it names: an output that is not registered, is sensitive or has no environment value, two outputs read from one variable, or no output at all.
InvalidLifecycle
A lifecycle block Terraform rejects: a data source (or one of its attributes) in replaceTriggeredBy, all inside IgnoreChanges.of, or a condition with an empty error message.
InvalidMoveTarget
A moved block whose to names no resource of the Stack.
InvalidTimeout
A negative timeouts duration.
LifecycleCondition
A precondition or postcondition block: Terraform fails the plan (LifecycleCondition.pre) or the apply (LifecycleCondition.post) with errorMessage when condition is false.
LifecycleOptions
lifecycle { ... } block on a resource.
LocalBackend
terraform { backend "local" { ... } } configuration.
MissingProvider
A block needs a provider configuration the Stack does not register: the provider its type implies (google for google_pubsub_topic), the one its provider meta-argument names, or one a module call passes on.
ModuleCall
A module "<localName>" { ... } call as a Dart value.
NeptuneClusterIdentifier
At most one of cluster_identifier, cluster_identifier_prefix on aws_neptune_cluster: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
NeptuneClusterIdentifierChoice
The NeptuneClusterIdentifier.clusterIdentifier choice: sets cluster_identifier.
NeptuneClusterIdentifierPrefix
The NeptuneClusterIdentifier.clusterIdentifierPrefix choice: sets cluster_identifier_prefix.
NeptuneClusterInstanceIdentifier
At most one of identifier, identifier_prefix on aws_neptune_cluster_instance: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
NeptuneClusterInstanceIdentifierChoice
The NeptuneClusterInstanceIdentifier.identifier choice: sets identifier.
NeptuneClusterInstanceIdentifierPrefix
The NeptuneClusterInstanceIdentifier.identifierPrefix choice: sets identifier_prefix.
NeptuneClusterParameterGroupName
At most one of name, name_prefix on aws_neptune_cluster_parameter_group: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
NeptuneClusterParameterGroupNameChoice
The NeptuneClusterParameterGroupName.name choice: sets name.
NeptuneClusterParameterGroupNamePrefix
The NeptuneClusterParameterGroupName.namePrefix choice: sets name_prefix.
NeptuneClusterParameterGroupParameter
Typed helper for the parameter block of aws_neptune_cluster_parameter_group (derived from provider schema).
NeptuneClusterServerlessV2ScalingConfiguration
Typed helper for the serverless_v2_scaling_configuration block of aws_neptune_cluster (derived from provider schema).
NeptuneEventSubscriptionName
At most one of name, name_prefix on aws_neptune_event_subscription: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
NeptuneEventSubscriptionNameChoice
The NeptuneEventSubscriptionName.name choice: sets name.
NeptuneEventSubscriptionNamePrefix
The NeptuneEventSubscriptionName.namePrefix choice: sets name_prefix.
NeptuneGlobalClusterSource
Exactly one of engine, source_db_cluster_identifier on aws_neptune_global_cluster: the provider rejects none and more than one, so each variant sets one of them.
NeptuneGlobalClusterSourceDbClusterIdentifier
The NeptuneGlobalClusterSource.sourceDbClusterIdentifier choice: sets source_db_cluster_identifier.
NeptuneGlobalClusterSourceEngine
The NeptuneGlobalClusterSource.engine choice: sets engine.
NeptuneParameterGroupName
At most one of name, name_prefix on aws_neptune_parameter_group: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
NeptuneParameterGroupNameChoice
The NeptuneParameterGroupName.name choice: sets name.
NeptuneParameterGroupNamePrefix
The NeptuneParameterGroupName.namePrefix choice: sets name_prefix.
NeptuneParameterGroupParameter
Typed helper for the parameter block of aws_neptune_parameter_group (derived from provider schema).
NeptuneSubnetGroupName
At most one of name, name_prefix on aws_neptune_subnet_group: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
NeptuneSubnetGroupNameChoice
The NeptuneSubnetGroupName.name choice: sets name.
NeptuneSubnetGroupNamePrefix
The NeptuneSubnetGroupName.namePrefix choice: sets name_prefix.
NoProviders
The Stack registers no provider, but declares resources or data sources.
ProviderConflict
Two provider registrations Terraform rejects together: two defaults of one name, a repeated alias, an alias that is not an identifier, or configurations of one name with different source / version constraints.
RefConstant<T>
The AppConstant.ref choice.
ReplaceTrigger
What lifecycle.replaceTriggeredBy lists: a resource of the Stack or an attribute getter of one. Resource and TfRef implement it; synth reports a data source or a data-source attribute as an InvalidLifecycle.
Resource
Base of every user-instantiable Terraform resource.
ResourceRef
Public for sealed pattern matching, but constructor is private — only TfRef.resource() may construct instances.
S3Backend
terraform { backend "s3" { ... } } configuration.
Sensitive<T>
What an argument Terraform marks sensitive takes: a variable, an expression or an attribute getter — a value Terraform resolves, never a Dart literal that would be written into main.tf.json.
SensitiveLiteral
A sensitive field is set to a literal, which would write the secret in plain text into main.tf.json.
Stack
User-extended IaC composition root.
StackBackend
Lightweight backend hook. Core ships GcsBackend, S3Backend, and LocalBackend; anything else implements this interface in the caller. The Stack only stores the value and exposes a discriminator for synth's terraform { backend ... } emitter.
StackProvider
Coordination interface between Stack (in this package) and concrete providers (e.g. GoogleProvider in terradart_google). Concrete providers implement every getter using their baked-in constants from Stage 2 codegen.
SynthIssue
One reason a Stack cannot be synthesized.
SynthResult
Bundle returned by StackSynth.synth.
TfAddressed
Anything that exposes a Terraform address, e.g. google_pubsub_topic.orders.
TfArg<T>
A Terraform argument: a Dart-side literal, a reference to another block's attribute (TfRef), a variable or a raw expression.
TfArgExpression<T>
A raw Terraform expression — the tf.json template string, verbatim.
TfArgLiteral<T>
TfArgVariable<T>
TfCollectionType
list(...), set(...) or map(...).
TfMoved
One moved { from = ... to = ... } block: the state object at from now belongs to the resource at to, so a rename does not become a destroy-and-create.
TfObjectType
object({ ... }).
TfOptionalType
optional(<type>[, <default>]).
TfOutput<T>
An output "<name>" { value = ... } block, registered with Stack.addOutput.
TfPrimitiveType
string, number, bool or any.
TfRef<T>
A Terraform-side reference: an attribute of a resource (AttributeRef) or a data source (DataRef), or a whole resource (ResourceRef).
TfTimeouts
timeouts { ... } on a resource or data source: how long Terraform waits for each operation before giving up.
TfTupleType
tuple([...]).
TfType
A Terraform type constraint: string, list(number), object({ name = string }).
TfVariable
One variable "<name>" { ... } declaration.
UndeclaredVariable
A TfArg.variable or var.<name> in an expression names a variable the Stack does not declare.
UnregisteredReference
A block references another block that was never registered on the Stack: built, but not passed to add(...) / addModule(...).
UnresolvableConstant
An AppConstant.ref whose value is not known at synth: the attribute is not set to a literal, is sensitive, does not match the constant's type, or belongs to a block that is not registered.
ValueConstant<T>
The AppConstant.value choice.
