Interfaces

Interface	Alerts	Modifiers	Description
DefaultProvider	`System`	`sealed`	Provides a default value for a field.

TypeAlias	Alerts	Description
_InlineTrick	`System`	Use for trick to "inline" generic types.
ApplyKind	`System`	Suitable for output. For input must error on side of excluding undefined instead.
ApplyKindInput	`System`	Suitable for input.
ExtractItemType	`System`	Get the `Item` type from a `LazyItem<Item>`.
FieldHasDefault	`System`	Type utility for determining if an implicit field schema is known to have a default value.
FlattenKeys	`System`	Return a type thats equivalent to the input, but with different IntelliSense. This tends to convert unions and intersections into objects.
FlexList	`System`	A flexible way to list values. Each item in the list can either be an "eager" value or a "lazy" function that returns a value (the latter allows cyclic references to work).
FlexListToUnion	`System`	Normalize FlexList type to a union.
InsertableObjectFromSchemaRecord	`System`	Helper used to produce types for: Insertable content which can be used to construct an object node. In this case, only own properties are considered. This reduces the risk of incorrectly interpreting data at the cost of occasionally requiring users to convert data into a compatible format. Insertable content which is an unhydrated object node. Union of 1 and 2.
NodeBuilderData	`System`	Given a node's schema, return the corresponding object from which the node could be built.
ScopedSchemaName	`System`	The name of a schema produced by SchemaFactory, including its optional scope prefix.

Variable	Alerts	Modifiers	Type	Description
