Ferrotype: Rust-to-TypeScript type generation via derive macro

This crate provides traits and derive macros for generating TypeScript type definitions from Rust structs and enums using an intermediate representation for deduplication and dependency ordering.

Core Design

The core abstraction is the TypeScript trait, modeled after serde’s Serialize. Rather than returning strings directly, it returns a TypeDef intermediate representation that can be:

• Rendered to TypeScript syntax
• Analyzed for type dependencies
• Deduplicated for cleaner output
• Extended for additional targets

Re-exports

pub use linkme;

Structs

Field

A field in an object type.

TypeRegistry

A registry for collecting and managing TypeScript type definitions.

Enums

Literal

A literal TypeScript type with a specific value.

Primitive

Primitive TypeScript types.

TypeDef

Intermediate representation for TypeScript types.

Statics

TYPESCRIPT_TYPES

Distributed slice for auto-registration of TypeScript types.

Traits

TypeScript

Functions

extract_object_fields

Extracts fields from an Object TypeDef, unwrapping Named if necessary.

inline_typedef

Extracts the inner type definition, unwrapping Named if necessary.

Derive Macros

TypeScript
