Rust error handling with thiserror and anyhow involves defining typed errors for libraries and applying ergonomic context at boundaries. This Skill guides standardizing error types, enriching propagation with contextual messages, and converting between Result and Option safely.

Choosing between Result, Option, and panic in Rust depends on recoverability. This Skill illustrates practical decision points for returning Result for expected failures, Option for absent values, and panicking for unrecoverable states.

Propagating errors in Rust with context uses anyhow to wrap failures with descriptive messages. This Skill demonstrates clear error propagation, adding contextual information at application boundaries to keep code reliable and maintainable.

Yes, this Rust error handling approach applies to both library and application code. It covers typed error design using thiserror for public APIs and ergonomic contexts using anyhow for internal application boundaries.

Rust error handling becomes verbose when error types lack standardization and context. This Skill solves inconsistent propagation by providing typed definitions with thiserror and standardized reporting using anyhow and Context.

Defining a custom error type in Rust uses thiserror to create typed, standard error enumerations. This Skill shows how to design these types and transition between error kinds to turn Rust errors into robust, safe code.
