## What it is
ts-rs is a Rust library with a derive macro that generates TypeScript type declarations from Rust structs and enums. It keeps backend and frontend types in sync by exporting bindings during tests, with serde compatibility and multi-file import support.

## Use cases
- generate typescript types from rust structs
- share types between rust backend and typescript frontend
- keep rust and typescript type definitions in sync
- export rust enums as typescript unions
- generate bindings for a wasm project
- generate typescript interfaces compatible with serde

## When to choose
- you build web apps with a Rust backend and TypeScript frontend
- you want types generated automatically from a single source of truth
- you use serde and want bindings to match your serialization
- you need multi-file exports with generated imports

## When to avoid
- your backend is not written in Rust
- you need runtime serialization rather than type declarations
- you want JSON Schema or OpenAPI output instead of TypeScript

## Facets
- artifact type: library
- maturity: stable
- function: serialization, developer-tools
- domain: web-development, developer-tools, apis
- platform: rust, cross-platform
- tags: typescript-bindings, code-generation, derive-macro, serde, wasm
