Fern's Rust SDK generator

Fern has introduced support for generating Rust client libraries from API specifications, aiming to streamline the development of performance-critical applications by automating the creation of type-safe, idiomatic Rust SDKs. This innovation addresses the demand from Rust developers for native SDK support and eases the maintenance burden by handling serialization, networking, and error management automatically. The generated Rust SDKs integrate seamlessly with modern Rust codebases, featuring async/await support, native streaming capabilities, and type-safe error handling, while minimizing dependencies. Fern's approach draws inspiration from established Rust SDKs like AWS's, using ergonomic patterns to ensure the SDKs feel native. Once an API evolves, Fern allows for effortless updates and publishing to crates.io, simplifying the integration process for developers. The first production customer, Payabli, reported a smooth setup experience, highlighting the SDK's robust type system and the convenience of not relying on numerous third-party libraries. Fern's SDK generator supports multiple languages and API specifications, including OpenAPI, AsyncAPI, and gRPC/Protobuf, providing comprehensive solutions for diverse development needs.
