Struct TypeRegistry 

pub struct TypeRegistry { /* private fields */ }

Type registry: maps type names to TypeDef and provides constructor-namespace lookup.

The constructor namespace is separate from the type namespace: a single lexeme can name both a type (Position — the n-variant union) and a constructor (Position — the sole constructor of that union). lookup_ctor walks the constructor side; get_type walks the type side.

Implementations

impl TypeRegistry

pub fn get_type(&self, name: &str) -> Option<&TypeDef>

Look up a type definition by type name.

pub fn lookup_ctor( &self, ctor: &ConstructorName, ) -> Option<(&TypeDef, &UnionMemberDef)>

Look up the union that owns a constructor name, plus the constructor’s payload fields. Returns None if the name is not a registered constructor.

pub fn all_types(&self) -> impl Iterator<Item = &TypeDef>

Iterate over all registered type definitions.

Trait Implementations

impl Clone for TypeRegistry

fn clone(&self) -> TypeRegistry

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TypeRegistry

fn fmt(&self, f: &mut Formatter<'_>) -> Result
