rust-errors

What problem does it solve?

Passing errors from Rust to TypeScript in Tauri apps is error-prone due to mismatched shapes and lack of a stable error contract. This Skill provides a pattern using internally tagged enums (discriminated unions) to ensure a consistent error structure across the Rust–TypeScript boundary.

Core Features & Use Cases

• Discriminated-union pattern for Rust-to-TypeScript errors using serde tagging (name field) to enable reliable error matching in TS.
• Clear Rust error definitions with messages and structured data, and corresponding TypeScript validation patterns.
• Guidance on serialization formats and best practices to maintain consistency across the boundary.
• Use Case: When a Tauri command fails, the frontend can discriminate the error by name and display user-friendly messages.

Quick Start

Define your Rust errors with serde tagging to create a name discriminator and handle them in TypeScript using a discriminated-union pattern.
