This article compares Rust’s primary error‑handling techniques—unwrap, unwrap_or_else, the ? operator, expect, and pattern matching—explaining their safety trade‑offs, appropriate use cases, and providing concise code examples to help developers choose the right approach for robust Rust applications.
Go 1.13 introduced new error‑handling utilities—Unwrap methods, errors.Is and errors.As functions, and the %w formatting verb—allowing developers to wrap, inspect, and propagate underlying errors more effectively, with examples illustrating legacy patterns, custom error types, and best‑practice decisions on when to wrap.
This article explains Go's built‑in error interface and the standard library errors package, covering how to create errors with New, unwrap nested errors, compare errors with Is, and extract concrete error types with As, including custom error examples.
This article explains Go's built‑in error interface, the traditional ways of creating and checking errors before Go 1.13, and the new errors.Unwrap, errors.Is, errors.As functions plus the %w verb in fmt.Errorf introduced in Go 1.13 for error wrapping and inspection.
