Struct EnumRegistry 

pub struct EnumRegistry { /* private fields */ }

Registry for enum definitions

Enables enum sum types by tracking which enums exist and their variants. Used for pattern matching resolution when matching against union types like type SaveError = NetworkError | DiskError.

Implementations

impl EnumRegistry

pub fn new() -> Self

Create a new empty enum registry

pub fn register(&mut self, enum_def: EnumDef)

Register an enum definition

pub fn get(&self, name: &str) -> Option<&EnumDef>

Look up an enum by name

pub fn contains(&self, name: &str) -> bool

Check if an enum exists

pub fn names(&self) -> impl Iterator<Item = &String>

Get all enum names

pub fn value_matches_type(&self, value_enum_name: &str, type_name: &str) -> bool

Check if an enum value belongs to a given enum or union type

For simple enum types, checks if value_enum_name matches. For union types (resolved from type aliases), checks if the enum is one of the union members.

Trait Implementations

impl Clone for EnumRegistry

fn clone(&self) -> EnumRegistry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EnumRegistry

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

Formats the value using the given formatter.

impl Default for EnumRegistry

fn default() -> EnumRegistry

Returns the “default value” for a type.
