Rust Error Handling
Result, Option, error propagation, and custom error types.
When to Use This Skill
Activate when:
- Returning and handling Result types
- Working with Option for optional values
- Using the ? operator for error propagation
- Implementing custom error types with Display and From
- Composing error enums with thiserror or adding caller context with anyhow
For Result, Option, ? operator, custom error type patterns, and the thiserror/anyhow ecosystem crates, see references/error-handling.md.
Anti-fabrication
This skill follows core:anti-fabrication. Every claim about Result/Option behavior, the ? operator, and the thiserror/anyhow crate APIs is verified against the official documentation and crates.io versions cited in sources.md — not inferred from generic familiarity with the ecosystem. Before asserting an error-handling pattern or crate API this skill and its references do not cover, check the installed crate version's docs.rs page rather than guessing.
