history

Project history and usage

Typeshare is a Rust-based developer tool from 1Password for generating matching type definitions in other languages from Rust source types. In package-manager catalogs it occupies the code-generation and FFI niche: a small command-line utility installed as `typeshare` for teams that want Rust-owned schemas to drive Swift, Kotlin, Scala, TypeScript, Go, or Python bindings.

Project history

The public GitHub repository was created in September 2022 under the 1Password organization. Its README describes the project as a way to remove the manual work of keeping FFI-facing Rust types synchronized with equivalent forms in other languages, using serde-oriented Rust definitions and a `#[typeshare]` annotation model.

By the 1.x series the project was organized as several Rust crates, including `typeshare`, `typeshare-core`, `typeshare-annotation`, and `typeshare-cli`. The README points users to a dedicated Typeshare book and documents command-line generation into Kotlin, Swift, Scala, and TypeScript files, with Go and Python marked as experimental in the official README.

Adoption history

Official public adoption evidence is mostly packaging and registry based rather than a broad ecosystem narrative. The input package facts list Homebrew and Nix packaging, while the upstream README advertises crates.io crates and the `cargo install typeshare-cli` path.

The project remained active after its initial publication: GitHub release metadata shows 2024 and 2025 1.x releases, including v1.13.4 published in December 2025.

How it is used

A typical use is to mark Rust structs and enums with `#[typeshare]`, then run `typeshare ./my_rust_project --lang=typescript --output-file=...` or an equivalent target-language command. The generated files become the foreign-language side of a Rust-centered serialization or FFI boundary.

Why package nerds care

Typeshare matters to package nerds because it turns a cross-language type-sync problem into an installable CLI workflow. It is especially relevant in Rust-heavy shops where package recipes, CI jobs, and generated artifacts need to keep mobile, web, and backend type definitions aligned without maintaining separate schema sources.

Timeline

2022: Public GitHub repository created under 1Password.
2024: v1.11.0 and v1.12.0 releases published.
2025: v1.13.4 published on GitHub releases.

Related projects

The README positions Typeshare around Rust, serde, and FFI/code-generation workflows rather than as a general serialization framework. It is related in practice to Rust procedural-macro crates and schema/codegen tools used to share types across language boundaries.
