Struct SchemaBuilder 

pub struct SchemaBuilder { /* private fields */ }

Mutable working set used while a graph is being built up.

Derived register_in bodies call SchemaBuilder::reserve before recursing into inner fields so back-references through SchemaType::Ref can close without infinite recursion. Once the body is fully constructed they call SchemaBuilder::commit to promote the reservation to a real definition.

Implementations

impl SchemaBuilder

pub fn new() -> SchemaBuilder

pub fn is_registered(&self, id: &TypeId) -> bool

true when id is already reserved or committed in this builder.

pub fn reserve(&mut self, id: TypeId)

Reserve a slot for id so recursive references close without infinite recursion. Must be followed by a matching Self::commit call once the body is built.

pub fn commit( &mut self, id: TypeId, name: Option<String>, metadata: MetadataEnvelope, body: SchemaType, )

Promote a reservation to a real definition.

metadata is attached to the body’s MetadataEnvelope (every SchemaType node carries metadata directly; the def no longer has a separate slot for it).

pub fn finish(self) -> Vec<SchemaTypeDef>

Consume the builder and return the accumulated definitions.

pub fn into_graph(self, root: SchemaType) -> SchemaGraph

Build a SchemaGraph using root as the entry point.

Trait Implementations

impl Default for SchemaBuilder

fn default() -> SchemaBuilder

Returns the “default value” for a type.
