Does this skill help avoid panics in Rust code?

Yes, it provides patterns to replace unwrap() and expect() with safer alternatives like match, if let, and Result combinators to ensure the application handles failures gracefully.

What is the difference between thiserror and anyhow in this skill?

thiserror is used for creating custom error types in libraries where specific error variants matter, whereas anyhow is used for applications where you want to easily wrap errors with additional context.

When does this skill suggest using the ? operator?

The skill promotes using the ? operator to propagate errors up the call stack, which keeps code clean and avoids deeply nested match statements for error handling.

How do I implement custom error types with this skill?

The skill provides templates for defining enum-based error types and implementing the Display and Error traits manually or via the thiserror macro.

开发者工具

Implements robust error handling patterns in Rust using Result, Option, and industry-standard libraries like anyhow and thiserror.

关于

This skill provides comprehensive guidance for managing errors in Rust applications, covering everything from basic Result and Option types to sophisticated error propagation with the question mark operator. It empowers developers to implement custom error enums, utilize popular libraries like thiserror for library-grade errors and anyhow for application-level context, and master combinators for clean, functional error handling. By applying these standardized patterns, users can ensure their Rust code is resilient, idiomatic, and production-ready while minimizing unrecoverable panics.
