Ferrotype: Rust-to-TypeScript type mapping for Zed RPC

This crate provides traits for generating TypeScript type definitions from Rust types, enabling type-safe RPC communication.

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

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.

Traits

TypeScript

The core trait for types that can be represented as 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

Derive macro for generating TypeScript type definitions from Rust types.
