generate typescript interface/type declarations from rust types


When building a web application in rust, data structures have to be shared between backend and frontend. Using this library, you can easily generate TypeScript bindings to your rust structs & enums so that you can keep your types in one place.

ts-rs might also come in handy when working with webassembly.


ts-rs exposes a single trait, TS. Using a derive macro, you can implement this interface for your types. Then, you can use this trait to obtain the TypeScript bindings. We recommend doing this in your tests. See the example and the docs.

get started

ts-rs = "7.0"
use ts_rs::TS;

struct User {
    user_id: i32,
    first_name: String,
    last_name: String,

When running cargo test, the TypeScript bindings will be exported to the file bindings/User.ts.


  • generate interface declarations from rust structs
  • generate union declarations from rust enums
  • inline types
  • flatten structs/interfaces
  • generate necessary imports when exporting to multiple files
  • serde compatibility
  • generic types


  • generic fields cannot be inlined or flattened (#56)
  • type aliases must not alias generic types (#70)

cargo features

  • serde-compat (default)

    Enable serde compatibility. See below for more info.

  • format

    When enabled, the generated typescript will be formatted. Currently, this sadly adds quite a bit of dependencies.

  • chrono-impl

    Implement TS for types from chrono

  • bigdecimal-impl

    Implement TS for types from bigdecimal

  • url-impl

    Implement TS for types from url

  • uuid-impl

    Implement TS for types from uuid

  • bson-uuid-impl

    Implement TS for types from bson

  • bytes-impl

    Implement TS for types from bytes

  • indexmap-impl

    Implement TS for IndexMap and IndexSet from indexmap

  • ordered-float-impl

    Implement TS for OrderedFloat from ordered_float

  • heapless-impl

    Implement TS for Vec from heapless

If there's a type you're dealing with which doesn't implement TS, use #[ts(type = "..")] or open a PR.

serde compatability

With the serde-compat feature (enabled by default), serde attributes can be parsed for enums and structs. Supported serde attributes:

  • rename
  • rename-all
  • tag
  • content
  • untagged
  • skip
  • skip_serializing
  • skip_deserializing
  • skip_serializing_if = "Option::is_none"
  • flatten
  • default

When ts-rs encounters an unsupported serde attribute, a warning is emitted.


Contributions are always welcome! Feel free to open an issue, discuss using GitHub discussions or open a PR. See CONTRIBUTING.md
