Which Rust libraries does this skill support?

This skill provides comprehensive patterns for the Rust standard library (Result and Option) as well as the industry-standard thiserror and anyhow crates.

Can it help with custom error types?

Absolutely. It includes patterns for simple custom error structs, complex enum-based error hierarchies, and implementing the From trait for automatic error conversion.

When should I use thiserror versus anyhow?

The skill guides you to use thiserror when building libraries that require specific, structured error types, and anyhow for applications where adding context to errors is the primary goal.

Does this skill help avoid application crashes?

Yes, it prioritizes recoverable error handling and idiomatic propagation, teaching the AI to avoid unwrap() and expect() calls that cause runtime panics.

API開発

Implements idiomatic Rust error handling patterns using Result, Option, and industry-standard crates like thiserror and anyhow.

This skill equips Claude with the deep expertise required to implement robust, production-grade error handling in Rust applications. It provides standardized patterns for working with the Result and Option types, propagating errors via the '?' operator, and choosing between library-focused error definition with thiserror or application-level context with anyhow. By guiding the AI to avoid unsafe patterns like unwrap() and expect(), this skill ensures that generated Rust code is reliable, maintainable, and follows the principle of 'errors as values' inherent to the language.
