Struct SchemaNodeSpec 

pub struct SchemaNodeSpec {
    pub content: SchemaNodeContent,
    pub metadata: SchemaMetadata,
    pub ext_types: IndexMap<Identifier, ExtTypeSchema>,
    pub type_codegen: TypeCodegen,
}

Trait for types that can build their schema representation.

This trait is typically derived using #[derive(BuildSchema)], but can also be implemented manually for custom schema generation.

Type Registration

Types can optionally provide a type_name() to register themselves in the schema’s $types namespace. This is useful for:

• Creating reusable type definitions
• Enabling type references across the schema
• Providing meaningful names in generated schemas

Primitive types typically return None for type_name(). Full node specification returned by BuildSchema::build_schema_node.

Mirrors SchemaNode but is used during schema construction to allow types to specify all node-level properties including ext_types and type_codegen, which cannot be expressed through build_schema alone.
