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. ### Sources - - - - - source_facts.package-manager ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** typeshare - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - typeshare: normalized package name match | nixpkgs package indexes: pkgs/by-name/ty/typeshare/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [quicktype](https://www.automicvault.com/pkg/brew/quicktype/) - Shares av.db curated category or tags: cli, code-generation, developer-tools, types. - [autogen](https://www.automicvault.com/pkg/brew/autogen/) - Shares av.db curated category or tags: cli, code-generation, developer-tools. - [cbindgen](https://www.automicvault.com/pkg/brew/cbindgen/) - Shares av.db curated category or tags: cli, code-generation, developer-tools, ffi, rust. - [configen](https://www.automicvault.com/pkg/brew/configen/) - Shares av.db curated category or tags: cli, code-generation, developer-tools. - [counterfeiter](https://www.automicvault.com/pkg/brew/counterfeiter/) - Shares av.db curated category or tags: cli, code-generation, developer-tools. - [cproto](https://www.automicvault.com/pkg/brew/cproto/) - Shares av.db curated category or tags: cli, code-generation, developer-tools. - [crcany](https://www.automicvault.com/pkg/brew/crcany/) - Shares av.db curated category or tags: cli, code-generation, developer-tools. - [create-api](https://www.automicvault.com/pkg/brew/create-api/) - Shares av.db curated category or tags: cli, code-generation, developer-tools. - [json2ts](https://www.automicvault.com/pkg/brew/json2ts/) - Local package facts share a topical domain.
