db library

AWS RDS DB instances, snapshots, and option and parameter groups.

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.

DataDbInstancesFilter
Typed helper for the filter block of aws_db_instances (derived from provider schema).
DataRef<T>
Public for sealed pattern matching, but constructor is private — only TfRef.data() may construct instances.
DbEventSubscriptionName
At most one of name, name_prefix on aws_db_event_subscription: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
DbEventSubscriptionNameChoice

DbInstanceIdentifierChoice
The DbInstanceIdentifier.identifier choice: sets identifier.
DbInstanceIdentifierPrefix
The DbInstanceIdentifier.identifierPrefix choice: sets identifier_prefix.
DbInstanceManageMasterUserPassword
The DbInstancePassword.manageMasterUserPassword choice: sets manage_master_user_password.
DbInstancePassword
At most one of manage_master_user_password, password, password_wo on aws_db_instance: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
DbInstancePasswordChoice
The DbInstancePassword.password choice: sets password.
DbInstancePasswordWo
The DbInstancePassword.passwordWo choice: sets password_wo.
DbInstanceRestoreToPointInTime
Typed helper for the restore_to_point_in_time block of aws_db_instance (derived from provider schema).

Typed helper for the s3_import block of aws_db_instance (derived from provider schema).
DbInstanceTarget
At most one of restore_time, use_latest_restorable_time on the restore_to_point_in_time block of aws_db_instance: the provider rejects more than one, so each variant sets one of them and a null choice sets none.

DbInstanceTargetUseLatestRestorableTime
The DbInstanceTarget.useLatestRestorableTime choice: sets use_latest_restorable_time.
DbOptionGroupName
At most one of name, name_prefix on aws_db_option_group: the provider rejects more than one, so each variant sets one of them and a null choice sets none.

Typed helper for the option.option_settings block of aws_db_option_group (derived from provider schema).
DbParameterGroupName
At most one of name, name_prefix on aws_db_parameter_group: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
DbParameterGroupNameChoice
The DbParameterGroupName.name choice: sets name.

DbProxyDefaultTargetGroupConnectionPoolConfig
Typed helper for the connection_pool_config block of aws_db_proxy_default_target_group (derived from provider schema).
DbProxyTargetDatabase
Exactly one of db_cluster_identifier, db_instance_identifier on aws_db_proxy_target: the provider rejects none and more than one, so each variant sets one of them.
DbProxyTargetDatabaseDbClusterIdentifier
The DbProxyTargetDatabase.dbClusterIdentifier choice: sets db_cluster_identifier.
DbProxyTargetDatabaseDbInstanceIdentifier
The DbProxyTargetDatabase.dbInstanceIdentifier choice: sets db_instance_identifier.
DbSubnetGroupName
At most one of name, name_prefix on aws_db_subnet_group: the provider rejects more than one, so each variant sets one of them and a null choice sets none.
DbSubnetGroupNameChoice

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.
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.
