export-type

A Rust proc-macro crate for automatically generating TypeScript type definitions from Rust structs and enums.

Features

• Export Rust structs and enums to TypeScript
• Support for generics
• Field renaming with rename and rename_all attributes
• Support for common Rust types:
  • Basic types (numbers, strings, booleans)
  • Collections (Vec, HashMap)
  • Optional values (Option)
  • Custom types
• Generates a single TypeScript file with all types

Installation

Add this to your Cargo.toml:

export-type = { version = "0.1.1", optional = true }

Usage

Use the #[export_type] attribute on structs and enums.

Example:

#[derive(ExportType)]
#[export_type(rename_all = "camelCase", path = "frontend/src/types")]
struct MyStruct {
    field: String,
}

#[derive(ExportType)]
#[export_type(rename_all = "camelCase", path = "frontend/src/types")]
enum MyEnum {
    Variant1,
    Variant2,
}

And you'll get a index.ts file in the specified path with the following contents:

export type MyStruct = {
    field: string;
};

export type MyEnum = "Variant1" | "Variant2";
