- Error handling in C is primitive, relying on global state and manual checks.
- Exceptions in languages like Java and Python hide failure paths, making errors hard to track.
- Go's error handling is explicit but verbose, with extensive boilerplate.
- Google's Absl Status standardizes error handling with canonical codes and macros for ergonomics.
- Rust's Result and ? operator provide clean error propagation with minimal boilerplate.
- anyhow and thiserror crates in Rust offer type-erased and structured error handling respectively.
- Error domain conversion in Rust can lead to context loss if not handled carefully.
- unwrap() in Rust is useful during development but should be avoided in production.
- Rust's debugging experience is hampered by lack of stack traces, relying on context annotations.
- Effective error handling requires organizational discipline and clear conventions.
