Rust to TypeScript Error Handling FAQs

Question 1

Do I need to use Arktype with this skill?

Accepted Answer

While the skill uses Arktype for runtime validation in its examples, the Rust patterns provided work with any TypeScript validation library like Zod or simple type casting.

Question 2

Why use internally tagged enums for Tauri errors?

Accepted Answer

Internally tagged enums create a flat JSON structure with a discriminator field (like 'name'), which TypeScript can use to narrow types naturally in switch statements.

Question 3

Can I use this for non-Tauri Rust projects?

Accepted Answer

Yes, these patterns are applicable to any architecture where a Rust backend communicates with a TypeScript frontend via JSON, such as WebAssembly or REST APIs.

Question 4

How does this prevent runtime errors in the bridge?

Accepted Answer

By enforcing a shared structure and using discriminated unions, the skill ensures that the TypeScript side knows exactly which fields are available for every specific error variant.

Question 5

What is the 'content' attribute anti-pattern?

Accepted Answer

Using #[serde(content = "...")] creates nested objects that are harder to handle in TypeScript compared to the flat structure provided by internally tagged enums.
