Rust to TypeScript Error Handling

Reference Repositories

• Tauri — Desktop app framework (source of Rust-to-TypeScript error patterns)

When to Apply This Skill

Use this pattern when you need to:

• Send Rust errors through Tauri commands to TypeScript clients.
• Define Rust enums that serialize into discriminated union error shapes.
• Validate unknown error payloads in TypeScript before switching on variants.
• Keep cross-language error payloads consistent with name and message fields.
• Avoid serde tagging patterns that produce nested, awkward TypeScript shapes.

Discriminated Union Pattern for Errors

When passing errors from Rust to TypeScript through Tauri commands, use internally-tagged enums to create discriminated unions that TypeScript can handle naturally.
