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

Reduce Rust error type boilerplate by using the thiserror crate to derive Display, From, and Source implementations automatically via #[derive(Error, Debug)] and #[error("...")] attributes.
Enable the ? operator for custom Rust error enum variants by applying the #[from] attribute, which automatically generates From implementations for seamless error conversions across variants.
Format Display messages for Rust library error variants by using thiserror's #[error("...")] attribute, which accepts inline string interpolation to provide precise, human-readable error descriptions.
Chain underlying errors in a Rust custom error type by applying the #[source] attribute to a variant field, establishing error cause semantics without generating automatic From conversions.
thiserror is primarily designed for library crates and public APIs requiring precise error variants with Display, From, and Source semantics, reducing boilerplate in ergonomic error definitions.
In Rust error handling, #[from] generates automatic From conversions enabling the ? operator, while #[source] solely establishes error cause chaining without creating the conversion implementation.
