thiserror

What problem does it solve?

This skill helps developers create ergonomic, well-typed error types in Rust using the thiserror crate, reducing boilerplate and improving error messaging by deriving Display, From, and Source capabilities.

Core Features & Use Cases

• Derive-based error implementations with #[derive(Error, Debug)]
• #[error("...")] formatting for Display messages
• #[from] conversions to enable the ? operator
• #[source] for error chaining
• Use in libraries public APIs to expose precise error variants

Quick Start

Provide a minimal Rust example that defines a custom error type with thiserror using #[derive(Error, Debug)], #[error("...")] for Display, and #[from] conversions.
